Performace Of Windows Inside Xen & VMWare VM
Sep 16, 2008I need several Windows VMs to test out some softwares and I plan on using virtualization technology to cut some costs.
I have a Linux(Debian Etch) dedicated server sitting to accomplish this.
Specs are Quad Core Xeon 2.13Ghz with 4GB Ram/500GB HDD.
Now if I were to choose between Xen 3.1 and VMWare Server for the virtualization technology which would provide better performance?
I tried Windows on Xen 3.1 with PV Drivers and it seemed some what slow, but I'm not sure what the case was there so I can't say which would provide better performance overall.
Internap FCP - How Much Does It Really Improve Network Performace
Jan 13, 2008I have been reading quite a bit lately about the Internap FCP. I am wondering how much it actually improves network performance and how it compares to BGP4. We currently use BGP4, but are considering using a data center with the Internap FCP for a project for a client.
I am looking for reviews from others who have experience with the Internap FCP and it's performance. How does it compare to a network using BGP4? I know that FCP uses more intelligent routing than BGP, but how big of an improvement does it make?
High Storage Hosting - 20 X 20 TB
Sep 24, 2009I need to put a proposal for a client who has 20 TB data storage (files/images).
Will propose PHP/mysql - mysql for meta data of files and other authentication etc. Application/mysql could just be ~10 MB.
The storage would increase (incrementally) ~ 1 TB per year.
And data needs stored at a different place for Disaster Recovery point of view.
Need to figure storage costing.
Please give me some pointers:
a) How to find high storage hosting provider?
b) Has any one experimented with Cloud Computing, and if so any ball park potential costing? I attempt S3 and could not figure costing.
c) or any other suggestion.

Aug 18, 2007Im currently with host gator and have nothing but amazing things to say but i have a music streaming website and its eating up bandwith like crazy but at least the cpu usage of the shared hosting is not that high but i will definitley pass my 2 terabyte mark within the month. My question is even on the dedicated hosting plans on host gator they still dont offer a lot of bandwith so does anyone know any very reliable and good companies that offer a LOT of bandwith for a moderate price. I was looking at liquid web dedicated which offers 3 terabytes as i hear their super reliable and professional

Mar 25, 2009What sort of redundancy that is recommended for a high risk site?
My definition of high risk is it will attract more hackers than usual, more DDOS, chances of blocked by ISP and etc.
High-End Complex Hosting Solutions
Jun 29, 2009Other than Rackspace, can the good folks here recommend some data-centers that have experience in handling the following solutions:
SAN (F/C, 10Gbps), 9TB usable capacity, complete redundancy, and real-time mirroring to an additional SAN in a separate geographic location.
redundant Brocade SAN switches
Servers: Quad processors, quad core, 48GB RAM, 8x146GB SAS Drives, multiple 1Gbps NICs
VMWare installations and handling.
Load balancers (preferably Brocade)
Dedicated L3 switches
I'm not just looking at providing this, but someone who can truly manage it 24/7 - management from VMWare and SAN perspective.
I saw some niche datacenters, but ran into the following problems:
(a) singular location.
(b) support for VMWare and SAN provided during business hours only
(c) no prior experience in real-time SAN replication / VMWare, Oracle/MS-SQL Replication.
High Quality Shared Hosting
Oct 13, 2008quality shared hosting solution for a WordPress-powered multi user blog. The blog currently has around 1000 posts, 5000 comments and around 2000 unique visitors every day, but those numbers will grow grow exponentially in future, so the hosting in question needs to be expandable since I will eventually have to move to a dedicated server.
Right now, however, I want a quality US-based hosting company that has good connection to EU, with fast support and basic features: PHP5, MySQL5, shell access, ~10GB HD space and ~50-100GB traffic.
First and foremost I am looking for quality and am prepared to pay as much as $25-30 per month.
Web Hosting That Specializes In High Bandwidth
Sep 14, 2008I have a dedicated server currently hosted over by Aplus.NET
I have a 3000 GB Monthly Transfer limit and we have been going over this limit for the past few months. This has resulted in a large sum of overage fees.
I am looking to go to another hosting company that is just as good as Aplus.NET, if not better... with a better traffic rate. A friend told me about Choopa.com and I wanted to know how good of a company they were. What are some other top reliable hosting companies with premium servers and that specialize in unmetered bandwidth?
Hosting A High Traffic Site
Jul 10, 2008We expect a site on one of our boxes to receive a significantly high level of traffic tomorrow as it is an event that will be covered and has already been covered by the press. The site operator expects > 100,000 hits a second.
It's a PHP page that pulls records from a database and lets people submit a form to insert a record. We have already put a caching script in place so that refreshing the page does not result in doing another database query.
The site was overloading a shared server, and we've moved it to one of our VPS boxes - it's the only VPS on the system at the moment. The box is a Quad Xeon 5410 with 4GB RAM with a 4 10K RPM drives in a RAID5 setup.
Recommendations For High-performance Hosting (clustering)
Jun 14, 2008I'd like to get your recommendations on how I should approach this problem. I posted this in another part of the forum, but I feel that this is a more appropriate place for it.
Problem:
How to handle large amounts of traffic with for a social network website? If a user uploads a photo or video, how does it become accessible on all of the server? If traffic is expected to be about 500,000 visitors a day, how many machines do you think I should use?
Possible Solution:
I've come up with the following possible infrastructure.
One load balancer. The load balancer has 3 PHP/Apache servers behind it. Behind each of the PHP/Apache servers is a (slave) MySQL server, from which data is read. Behind the slave MySQL servers, there is 1 master MySQL server, which handles all of the database writes. The master MySQL and slave MySQL servers are synced up, so data is up to date.
The actual photo and video files are not stored in the database, only the links to them is stored in the database (to keep the database small). The photo and video reside in a central location (like a SAN or NAS), which is accessible by all of the 3 PHP/Apache webservers.
Questions:
1. How many machines do you think will be able to handle photo and video uploads for 500,000 visitors a day?
2. Is having a SAN with Terabytes of RAIDED disk space an available option?
3. If a SAN or NAS is not an option, does anyone have any ideas on how to make sure all of the web servers have access to the same photos and videos? Is rsync a viable solution?
4. Which hosting provider do you think I should go with?
5. Is clustering what I need? What is clustering and how will it address my concerns?

Shared Hosting With High Reliability Email
Jun 24, 2008Is there any conventional wisdom on WHT about which shared hosting providers have highly reliable email service?
The provider I have now has very good web hosting service but their email services tend to bitbucket far too much mail for comfort. Reliable delivery and reception for the half a dozen emails I might send/receive a day (it's a personal use site) is I hope not too much to ask without needing to pay and arm and a leg for the privilege.
Creating A High Traffic Hosting Setup
Oct 3, 2008creating a setup that will host a site which is expected to receive 50-60K visitors in the first few hours after its launch. The site is membership based and the backend (member system) runs on PHP5-MySQL5.
Here is what I have thought of until now.
Site's sales page (which also happens to be the first page that visitors hit) hosted with Amazon S3 service. All public media files are off loaded to amazon S3 service to keep the number of requests on the hosted setup to minimum.
At the front we can have a high performance firewall like Cisco ASA 5520 followed by two dedicated load balancers in Active/Active state.
Behind the load balancers we have 3 front end servers acting as web-servers. These have SAS disks, 4GB RAM, RAID 1 setup, Dual Xeon Quad core processors each.
Behind the front end servers - we have a dedicated load balancer for the database cluster.
The database cluster consists of 3 Storage/API nodes and one of the front end servers acts as the management node. Each storage node has 8GB RAM, Dual Xeon Quad core processors, 4x RAID 10, SAS setup.
The private network is on a GigaLan.
Do you see any possible/obvious flaw in this design or anything that should be added/subtracted from the setup?
Cheap High Transfer/bandwidth Hosting
May 22, 2008I know you get what you pay for with hosting, but with the ridiculous overselling going on I am finding it hard to work out how much bandwidth I can genuinely expect to get with about 500MB space and 99%+ (preferably more like 99.5%) uptime for $5/month.
I will be using all this bandwidth for hosting legal mp3s (sanctioned for promotional use by labels and artists), and would prefer the host to be based in the US or UK.
Any Experience With GoDaddy.com Dedicated Hosting? (I Need High Bandwidth)
Jul 20, 2005I'm currently running a vBulletin message board with about 26,000 members. At any given time there are about 200 members actively posting.
Right now, we're on a dedicated server with Ilon hosting, however, my members are still complaining that the site runs VERY slowly when there are lots of members online.
To make matters worse, I want to launch a weekly podcast for them, so I'll need even MORE bandwidth.
GoDaddy.com is offering dedicated server accounts with high bandwidth limits (ie 2000 GB). Does anyone have any experience with them? ...

High Traffic Hosting Solution (dedicated Server?)
Jul 23, 2007I'm working on launching this online store for a poster designer, and we're becoming more and more aware that we need a really robust and fast server. This site is looking at extremely high levels of activity whenever this designer posts a new poster. We're talking 1700 people surfing the store (downloading med-high resolution poster images) and 300 posters sold in 16 seconds kind of thing.
So, we need a really robust hosting, to work with PHP5 and MYSQL.
My previous go-to hosting provider was Lunarpages, but their customer service has gone down the crapper, and I've just about had it with them. My main questions are:
Should I be looking into getting a dedicated server, or are there hosting companies that can handle this kind of traffic on a shared server? I don't have experience administrating a server, so if we got a dedicated one we would have to pay the host to do at least some of the setup/administration, I would assume?
Dedicated server or not, what's a hosting company that has really good customer service, where we can be assured of getting somebody knowledgeable without having to wait on hold for 20 (or even 10) minutes?

High Server Load / High Swap / Lots Of Httpd
Feb 20, 2008I have a cPanel server with 4GB RAM
My server hangs time to time, once or twice a day. This is the last status when it happens.
Server Load 75.90 (2 cpus)
Memory Used 92 %
Swap Used 65.78 %
When I was still inside SSH when it happens, the processes I can see inside "top" are a lot of httpd processes.
So I "killall -9 httpd", I had to do it 30~40 times
#killall -9 httpd
#killall -9 httpd
#killall -9 httpd
x 30~40 times until no pid process found & the server load is back to normal.
Before that, I check httpd fullstatus, they look very normal, same goes to what I see inside WHM Apache status & cpu usage status.
At first I thought it was a memory problem after consulting with a server admin, so I replaced all 4GB new ram stick (such a waste)
Plesk 12.x / Linux :: High Memory Usage - Swap So High
Nov 14, 2014This is my free -m

Mem: 1998 1903 95 0 45 542
-/+ buffers/cache: 1315 683
Swap: 2662 36 2625
Not good ....
I got 5 wordpress and 5 statics website on this server and 100 visitors by 24H00 each day.
Question 1 : Why the memory is so low and the swap so high ?
Question 2 : Why i don't find high usage process in top command ?
Question 3 How can i resolve this problem ?

Server High Load/high Mysql Usage
Jul 2, 2009I have a site that is eating up my server resources and need to know what the best solution for this is. I'm thinking of getting another server just for mysql but do not know what specs the server should be to handle the current traffic/database load and have the site run smoothly without slowing down to a snail's pace.
An alternative is to get another server just for the videos being served and leave the database and html on the current server. This is where I'm stuck and don't know what route to take with this.
My current server stats:
Dual Xeon 5130
4GB RAM
250GB
50 Mbit/sec
CentOS 3.9
Website traffic stats:
15,000 visitors/day
150,000 pageviews/day
Serving videos
I've attached screenshots of top and bandwidth usage per day. Hopefully with this information you could tell me if I need another server or if there are any things I can do to the current server to help things move faster.
High Load From High Iowait
Jul 2, 2008I am running in a High load problem lately. I have one of those cheap 1and1 servers which was running fine until 2 weeks ago. Once I rebooted accidentaly, it did not come back with some unrepairable kernel errors and I had to re-image it.
I chose to reimage the server with CentOS 5, for better support. The new re-image worked fine for some days, at least so I thought and now I am having high loads. The server crashes if not monitored every moment as the load is unpredictable.
Just a restart of the Apache will bring the server back to normality, but I am not sure if it is apache or some other script to be blamed.
I have beeing monitoring through apache server-status, but I cannot organize something unusual in the high load moments.
At this moment for example:
top - 09:00:36 up 15:43, 3 users, load average: 3.57, 4.60, 5.32
Tasks: 144 total, 2 running, 142 sleeping, 0 stopped, 0 zombie

=====================================
lsphp is my webserver (litespeed). The sleeping processes are my SHOUTcast servers.
The thing I am concerned about is the "94.3%ni". This is slowing down my server completely and I am not too sure of what it is. Can anyone shed any light on this?
High VPS Load
Jun 24, 2009My VPS holds about 80 domains and low-use accounts.
Every night, from around 1.30am, the load suddenly skyrockets and will usually be around 5 to 10 for a few hours. Occasionally it'll spike to 30+ for a few minutes.
I had some antispam software running, and a couple of other packages (mail queues, mail manage etc), so I disabled all of that and removed all the crontab entries etc.
It's not really made any difference.
I can see the load stats going back 8 hours, as part of the ASSP spam package (I've just left the ASSP server load cron running just so I can continue monitoring it!)
Can the apparent load on my VPS be caused by other VPS's on the same node?? So in reality, my load is fine but is being affected by other people's VPS's?
I hope that makes sense. I'm 99% sure that my VPS is 'clean' (in so far as cron entries)
I'm asking the question because I took a second VPS on the same node and that one too has high loads overnight when there's nothing running on it (ie, no add-on software, no Cpanel accounts added)
What Causes High Load
Apr 19, 2009I have a VPS with LXadmin control panel and 1024 Ram.
the memory always 333-450 but now it is more than 800 and the VPS stopped I restarted it many times but after restarting it the memory gone crazy again.
So, how to know what causes high load and eating my Memory?
