I saw there are some providers offer high end xen VPS with like 2-4G memory, I am wondering is there any advantage of such a high end VPS comparing with a regular dedicated server? suppose both servers have same price.
What kind of web site is suitable on such a high end xen VPS? say, database extensive or disk operation (read/write) extensive?
I am facing high ping and packet loss issues with a server hosted at hetzner.de (CentOS + WHM)
For some unknown reason pings go high and stay like this (average 1500ms) until I reboot the server.
Here is a screenshot of tracert from server to me: [url]
I have a site that uses extreme amounts of bandwidth, I checked some of the popular companies like serverbeach and softlayer. Right now I'm leaning more towards serverbeach because they are cheaper, Are they a good company to go with? Let me know if you have any other recommendations.
View 14 Replies View RelatedI'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?
I have been trying to identify why mi server has high load cpu, suddenly CPU load suddenly jumps, from 1 to 40 and until 110
If I restart mysqld and apache, the cpu gets back to normal, until this happen again
My server is
GenuineIntel, Intel(R)Core(TM) i5-2400 CPU @ 3.10GHz
VersionParallels Plesk Panel v11.0.9_build110120608.16 os_CentOS 6
CentOS 6.4 (Final)
CentOS 6 x64 Processor: Intel Core i5 - 3.10 GH
I already installed FAIL2BAN and DDOS DEFLATE without lock. I have CloudFlare Enabled.
When there is a high CPU load, I have checked netstats, and I don't identify many ips connected, so I think it could be an internet script (or virus).
I will paste the result of
ps fax
command, in a moment of high cpu load
I 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)
My server is very slow, High CPU, High Apache load....
I got a new server and i had setup a script on it.
No server tweaks has been done.
I run a filehosting site so it gets very slow when traffic is high.

I dont know much about server managment...
how to fix this so server doesnt go slow?
I 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.
As a non-tech but looong term sufferer in the Hosting biz both as a consumer and VERY briefly a supplier ( strictly for masochists IMHO ), over the years I found it was only specific individuals - not the Hosting Company that was the key point.
Good support people are really needed more today than ever before. It is sooo complex - as follows:
We are looking at leaving our unsupported VERY small Dedicated Server after two years of frustration trying to get a secure, reliable system going without success. A mixed bag of problems: Us being non-geeks, OS problems, Server problems.
We are looking at going back to a VPS in the light of amazing claims being made for them today.
A fraction of the cost of Dedicated and yet *claims* of astounding capability. CLAIMS...
That's why I'm here today with you. I need help sorting the facts out. Can a VPS that : is "burstable" for RAM and with amazing pipe access and volume allowance and the new concept of "sorta like load balancing" sharing workload over possibly hundreds of Servers in a giant cluster" actually be real?
If this is true it would be Server heaven for me as the Provider has to do all the Geek-stuff!
I want new company for my servers
My servers for sharing files
So, I want high bandwidth

I'm currently running vBulletin & two wordpress powered blogs on my box. Number of simultaneous users is about 200~250 and about 15~20 logged in users.
The memory usage is constantly in the range of 1.8 GB - 2.00 GB. Considering that total physical RAM my box has is 2 GB, the memory usage, I believe is exceptionally high.
The same site was running very well on shared hosting environment and also on VPS [with just 512 MB RAM] very fine.
What should I do to bring the memory consumption to minimum (required to run the site well?)
I'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? ...
hosting solution for 3 very high traffic blogs, all running on WordPress.
I have been researching dedicated and I came across a couple posts where people recommended Clustered hosting over Dedicated for better handling high traffic DB driven sites in the times of Digg or Slashdot frontpage exposure.
I would like your feedback, and your opinion on what to choose from the following options:
1. Netfirms Enterprise III (Clustered)
2. ResellerZoom Failover (Clustered)
3. LiquidWeb Dedicated Webmaster Series (Dedi w/ 2GB DDR and a 3Ghz Intel Hyperthreaded)

Question 2 : Why i don't find high usage process in top command ?
Question 3 How can i resolve this problem ?
What is the difference between Dedicated Virtual vs Regular Dedicated Server?
Also what are the pros and cons of going with Virtual?
do you know what my server having very strange problem my server load suddenly increas after every 2 or 3 days some time after 1 days but when we talk about those days in which server load is fine then that time server load very low almost 0.4 to 0.1 .
But on that high load day server load reached upto 500.
when i try to find out what wrong then i only get that there is too much connection of http when i kill httpd through this killall -KILL httpd then server load suddenly decrease and then stable.
I have a Quad Core Xeon server with 2 GB RAM. The server has some high traffic websites & at peak hours (4-5 hrs a day) the server load remains 10.0 to 50.0.
The sites on the server load very slow at these times. Here's the top result during heavy load

We are having a problem with our Linux dedicated server. At time we are getting high server loads witch is causing the server to go down and reboot. This problem has been going on for over a month now and still liquid web can not tell me what is the cause of the high loads. We have upgraded our RAM to 2 GB. This look to fix the problem for the first week but now we are back to having high loads and downtime.
I'm not a IT person so do not know how to find the problem. Can anyone tell me what I can do the locate the problem. I do know how to access and do some things in the root but do not know enough to find and fix this issue.
I have a dedicated server with godaddy. Yesterday it went down. I sent a trouble ticket to their support. In 4 hours I got reply saying that everything is fine and server is just experiencing high bandwith. I was able to login to control panel (which is available through different IP address, and I have noticed that my usual 8 gigs a day bandwidth increased to 160 a day for yesterday. I cannot SSH to my server. I cannot access my website via http. I cannot FTP to my server. I cannot do anything. I have submitted another ticket and waiting fro reply.
Any suggestions? Is this an attack? (I feel it is, but not sure) What kind of attack can bring server down, if I have CISCO firewall installed? I am little upset with godaddy, because so far, my server has been down for over a day. Any providers out there, who are more rapid in terms of helping their customers? FYI: I pay them $150 a month.
the site is running fine..
i have increased my maxclients from 256 to 320 ( reset all same ) my load has increased from avg 3 to 8.. is it a prob?
I've got a server that suddenly over the last three days has exploded as far as server load. Watching top I have some httpd processes that are using up all of the cpu and lasting for quite some time.

View 13 Replies View Relatedi have ideas about clustering server with spread country/datacenter.
example: i have 5 Server spread around the world, server 1 in US, server 2 in German, and other country for next server.
server 1 will be main server, when server 1 down, it will goes to server 2, and continue to the next server.
all site/file and other stuff will be mirror on all server.
so it will be 100% Uptime!, and never LOSS anything!.
and my question is how to do that, maybe someone expert want to share with me.
Server load is under 1, nearly 0 io.
Ping between 200-300, normally it is around 50.
DC says their network is fine and it is my server.
So load under 1, almost no hard drive access, why is the ping so high?
Whenever I run the "top" command, I see that some of the user "mysql" records always have very high CPU usage, anywhere from 20-80% on average (I've seen 100%). There are multiple records that show this, which means that the CPU is always above 100%. My cacti monitoring account also shows messed up CPU statistics.

I told my system manager about the cpu problem, and he said that he installed the cpulimit function on my server. I'm not sure if this is a good solution.
We have an abnormal server load because of clamd.
View 4 Replies View Relatedif upgrading to that new server that I'll mention will probably solve my problems. Whatever help you can provide would be greatly appreciated. Below are the details:
In the GMT evenings and nights my current server gets so loaded that every page load takes 10 - 30 seconds. Even the pure html pages will be so slow to load. It seems that after a certain treshold it just suddenly becomes that much slower. Not much middleground there. I have high MaxClients and ServerLimit values now and the error log doesn't say that they are exceeded anymore but that didn't help enough.
I have a high traffic website that is using latest version of apache (2.2.x) with the prefork MPM and apache is optimized, PHP 5.2.5 and APC 3.0.15.
I get 160,000 - 210,000 pageloads per day. 32,000 - 45,000 visits per day.
Most of its pages are PHP but shouldn't be too CPU or databes intensive. Mysql isn't used and I mostly used sharedmem (php's shm functions) for databases. 2 semaphores are quite heavily used but that can't explain how a few more users would make the server serve pages so much slower.
Swap usage is practically 0 and CPU user % usage is like 1 - 2 % and CPU system % is also about the same even during peak times. However the Average Load or whatever that "top" reports is 6 - 9.
My current server scecs: 1 GB Ram, Pentium D 3 ghz, CentOS 5 32bit fully updated.
I load all pictures and even the stylesheet from a secondary server by using href="$secondaryserverIP..." in the html code, so the main server practically just serves the pages.
My new server will have apache with the worker MPM and latest versions of every software. Also its specs are: 2 GB of RAM, Intel Dual Core Xeon 2.40GHz, CentOS 5.1 32bit fully updated.
I have a sophisticated netstat based ddos script that is an improved version of DDoS Deflate and while some of these slowdowns seem to have been caused by attacks that it then was able to defend me from, most of them are not. I am even protected from users who constantly have 7+ connections to my site and if someone has a way too high number of connections, the script won't even check if it constantly has it and the script just bans that user outright. It probably is banning a bunch of innocent proxy users too but that is a small price to pay.
