Improve Performance- Web Server, SSH Server, And Mail Server

May 8, 2007

I've got a VPS which is serving as the main server for a number of sites. Web Server, SSH Server, and Mail Server.

What I've got running:

Apache2, PHP5, MySQL5, Dovecot, Postfix

One of the sites is a growing forum with a MASSIVE photo album. This is the site where I notice the most slowness.

Changing the server software is not an option - Only optimization.

Does VT Improve The Performance Of VMWare Server

May 4, 2009

The newer Pentium 4 3.0 GHz processors had so called 'VT'-support. That's something every regular processor has nowadays.

I currently run a Pentium 4 3.0 GHz server without VT. Will there be a drastic performance boost if I use a Pentium 4 3.0 GHz with VT?

What is VT anyways? I only know that Xen requires it if you wish to host a Windows Virtual Machine on a Xen Linux Server.

What Can I Do To Improve Bandwidth / Uplink Speed Of Server

Oct 4, 2008

As per topic, what is the best method to do to the hardware to improve bandwidth / uplink speed of server?

I have a production server that is used for regular file serving.

P4 3.0Ghz
500GB + 160GB + 160GB hard disk
2Mbps Dedicated + 10Mbps shared.

However, the most I can pulled through the whole server is always between 1.5Mbps - 3Mbps, anyway to pull the speed up to around 10Mbps should there be availability of bandwidth for me to burst?

For any informations, the hard disk is SATA 2.

Load On Server Decreasing Server Performance

Oct 11, 2008

We have CentOS 4 and WHM 11 on server .

Now-a-days server is having too much load due to http and in access logs we see following message :
======================================== - - [11/Oct/2008:01:40:02 -0700] "OPTIONS * HTTP/1.0" 200 - - - [11/Oct/2008:01:40:03 -0700] "OPTIONS * HTTP/1.0" 200 - - - [11/Oct/2008:01:40:02 -0700] "OPTIONS * HTTP/1.0" 200 -=============================================

And due to this there is load on server. We are not able to understand why this is happening and how to stop this. So please suggest with some solution.

VPS Performance / Server

Apr 12, 2009

We are getting into VPS hosting and wanted to get some opinions and feedback as we're quite unsure on what to expect as for performance and how many clients we can generally keep on a box.

For now we've bought 3 dell R710 with dual Xeon L5520, 72GB ram and 8 x 2.5" SAS drives.

We are thinking of a base offering of 512 megabytes of ram and
was hoping to get about 40-50 onto a server.

With 40 there should be -plenty- free ram and plenty drivecache.

Then a next offering of 1 gig ram and next one of 2 gigs.

Even if we do the biggest 2 gig offering with 25 on a server we should have free ram to spare.

The software would be virtuozzo.

Any thoughts on this, am I expecting too much, or am I being fairly realistic?

Server Performance Optimization

May 7, 2009

Hi"Optimization of computing resources has long been an important management issue. One of its aspects concerns server scalability and the question of whether an organization should scale-up or scale out.Assume that the computing performance of the servers can be measured by variable 0 <=p, that their total cost is given by "c" and the relationship between server performance and cost is defined by c=&#945;p^&#946;"

a. What is the cost-performance elasticity(&#1106;), precisely?

b. What would be the range of values for &#1106; that would be expected by moore's law and what are its implications?

c. What would be the range of values for &#1106; that would lead managers to scale-out? Draw a graph and throughly explain the implications.

Worldwide Server Performance

May 2, 2009

We are a web-based Yacht Charter company, with offices scattered around the world:

Currently, both our web site and our back-office business management system are hosted on a single server in the UK, with an automatic fail-over to a server in Dallas, TX, USA.

The problem we are having is that our sales office in Singapore is having really slow response times and this is very frustrating for them.

Using an application called "JustPing" we see that response times From Singapore are much slower than other parts of the world. (the cities closer to London are fastest, the ones further away are slowest)
JustPing Results

Is there anyway to improve this or is hosting our applications on multiple servers the only way to improve performance. What's the best cost-effective method of multiple server hosting?

(Incidentally, if I JutPing Google, response times are fantastic worldwide, but we know they're hosted on many, very large servers)

Litespeed Server Performance

Sep 29, 2009

I was just playing around with litespeed and I thought I would switch back to apache for a few min to see how the server reacts. The load with litespeed was 1.00 - 3.00. I switched to apache the load jumped to 28.00 - 35.00. Its amazing how litespeed is handling connections.

Web Server Performance Testing

Jun 15, 2008

Is there a site which will enable me to enter url of my website and it will simulate visitors from multiple locations. It needs to open the page completely, and run for example 10 minutes. Two things I found are host-tracker, but it just gets headers from multiple locations, and does it only once. Another thing is Paessler software which can test exactly what I want (number of visitors for some period of time with full page download) but it must be run from one (my) PC, so I can not test bandwidth from multiple locations. I need combination of these two, anyone knows for something like that on the net?

Monitoring Server Performance

Aug 17, 2008

My dedicated server is sometimes sluggishly slow. I would like to get a grasp of its performance during a day, to get a better understanding of what's going on.

Therefore I am looking for a server performance monitoring service. All service I found so far were simply monitoring uptime (server is down / server is up). I need something more - a service that checks every 30 seconds or so the loading time of the main page.

Then it would allow me to download the data in CSV or draw a response time graph.

How To Monitor My Web Server's Performance

Jan 8, 2007

I've recently found (last 6 weeks) that the performance of my client's websites on my trusted host's servers isn't how it used to be and/or how it should be. The download seems to take way much longer than before. So far it hasn't resulted in a significant drop in average pageviews per unique visitor but it might do if things continue. The host claims a number of attacks on the mailserver and an unusually high load at one point in time. Above all it's just annoying - isn't reliable server performance what can be expected from a reputable host?

Here's the question: what's the best way of monitoring online how the web and mail servers are performing so that I can take this report to my host and urge them to take (more) action? Ideally I'd like to compare this with a seperate web server that I use for another client. I don't mind spending a little bit of money but high subscription fees are not in my budget.

Multi Server Setup For DB Backup Performance

Jan 8, 2009

I am working on a busy and popular website which has a large amount of database activity - and requires hourly backups of all database data.

At the moment the site is hosted on two servers - one for the front end web server, one for the database.

Both servers are running a RAID HDD system which allows quick swaps of faulty HDDs without data loss.
An hourly full backup of database tables is running which is killing the server when it runs.

ISP has suggested installing a third server to run as a slave to the existing DB server, and hence always hold a duplicated of the live database.

I have a feeling however that this is basically just like having RAID mirroring, but on a different machine - so to solve the problem of a potential dodgy SQL statement wiping out ALL copies of the live database, we'd STILL need hourly backups to run, and hence would still see the major system speed drop each hour at the time of backup.

High Server Load And Slow Performance

Mar 11, 2009

I am currently hosting my website on one server with the specs:

2.8ghz Dual Quad-Core processor + 8 gigs of ram + two 500 hard drives with a 50 mbps unmetered bandwidth package.

My current problem lies in high server loads and very slow server performance throughout the day.

I am considering migrating over to The Planet onto server with the specs:

3.0ghz Dual Quad-Core + 18 gigs of ram + two 50gb hard drives with 2TB of monthly bandwidth transfer.

In an attempt to have great bandwidth pricing and server performance, I plan on downgrading my current server with my current host to a lowe-end server and keeping it only to host my VIDEO and MUSIC files with the 50mbps unmetered package. The Planet will then host my database and all other web related files on their new server.

Is this a good idea as an attempt to save money in bandwidth costs and eliminating my server lag issues?

I was offered a setup of a separate web and database server at my current host but from what I have read, no one touches the performance and reliability The Planet has to offer.

Windows 2000 Advanced Server Performance

Nov 27, 2007

I have a Windows 2000 Advanced Server where there's a performance issue with some of the .asp pages that retrieve data from Access databases, (I know Access databases aren't ideal for data). These pages will just get stuck/freeze, and then either suddenly spring back to life, or give a script timeout error 0113.

The largest Access database I've seen is 136MB (is that way too large?)

I will probably move some of the large Access databases onto a different server but before I do:

- Are there any tools you can recommend to diagnose exactly what files / databases are causing the problem. I don't think the Win 2000 performance monitor tools even work.

- Can anyone explain more about the technicalities behind this issue. I expect it has something to do with processes, threads, memory, Access drivers being loaded into memory etc etc. Can anyone tell me what they know to put me in the picture better?

Apache :: CentOS - Measuring Performance Of Server

Feb 25, 2015

I have centos -7 and apache 2.4.6. I have made one small php scripts and measuring the performance of server.

Average time is around 15 ms for per request. But when adding concurrent requests the average time increase too much high for the request see the below output

ab -n 10000

Connection Times (ms)
min mean[+/-sd] median max
Connect: 0 0 0.0 0 0
Processing: 14 17 2.6 15 35
Waiting: 0 1 0.2 1 10
Total: 14 17 2.6 15 35

With Concurrent connections

ab -n 1000 -c 100 See the processing the mean request time its around 150 ms.

Connection Times (ms)
min mean[+/-sd] median max
Connect: 0 0 1.1 0 5
Processing: 25 150 24.7 153 213
Waiting: 2 134 25.2 138 194
Total: 29 150 24.1 153 216

ab -n 1000 -c 100 See the processing the mean request time its around 150 ms when total request is 1000 only.

Connection Times (ms)
min mean[+/-sd] median max
Connect: 0 0 1.1 0 5
Processing: 25 150 24.7 153 213
Waiting: 2 134 25.2 138 194
Total: 29 150 24.1 153 216

How to configure the Apache so the request time decreas to low ms ???

In Centos -7 Default configuration of MPM Directory also not found ??? checked in httpd.conf and other file also.

Mail Server And Dedicated Server Configuration

Aug 6, 2008

I'm a a JAVA software developer and it happens that I need to configure a dedicated server running Win 2003.

It's already up and running with static IP address, however hosting offers a "Static IP Address", which doesn't really make sense, cause I already have one?

Other thing is domain name. Current domain name is registered with a different company and we don't really want to transfer it from that company. Can I get away with importing a domain name and changing MX records in the domain control panel?

Last thing is an email server. What do I need to set up an Email Server? I have a domain name with few POP3 email addresses. I thought about using hMail server for windows. What else do I need to do, pay for?

Realtime Transfer Of E-mail From Server To Server

Mar 28, 2007

I have a vps (CPANEL)... I would like to have incoming emails for a certain cpanel account transfer to another external server (after coming thru the VPS).

I store my emails on the external server and have more space there.

The reason behind this is:

I have spamassassin on my VPS and would like to run email thru that before it delivers on the external server. I do not have the capability to install spamassassin on the external server.

Is the above possible? How can I accomplish this?
