I'm preparing this week's tech tutorial, which will be on getting more out of your web server. However, unlike MySQL, there's not really a single obvious web server that everyone's likely to be using.
So - please take a second and tell me what web server you're running for your campaigns and tracking? If you're using several, tick all that are appropriate!
I shall, in turn, deliver some fine, fresh-baked optimisation tips in a couple of days!
Got a few VPS and shared hosting.
a U1 rack server colocated.
I started out years ago with FreeSCO running on a pentium with 500mb hdd 
umm this is a stupid question but how do you tell? is there a fast way to find out all ur server details?
@vidivo - there are no stupid questions!
This tool seems to work pretty well to tell what server you're running: http://www.yellowpipe.com/yis/tools/craftnet/
If you don't know its probably aposche.
I think a large portion of the forum members use beyond hosting vps/dedis.
Good point - I probably should have asked that.
Is anyone running LiteSpeed, but NOT on Beyond Hosting?
nginx
Nginx
I am using Nginx, HAProxy , Openlitespeed, apache.
Sever never been bottleneck for me atleast. I don't like premature optimizations. Often DB is bottleneck. Better analysis is needed to detect bottleneck and remove ( or improve ) it from system.
But, i have personal preference for Ningx for its easy configuration. Devloped by a guy with taste. I don't like other closed source or patch work stuff.
What are you guys using for your load testing?
loadimpact.com is good but they are expensive $$$.
Apache, but a tutorial on using and setting nginx would be appreciated!
Tweaked apache, still running fast enough.
I'm a fan of Blitz.io for simple load testing - although if you want to get really hardcore about your load tests, you either need a multi-server JMeter setup or, as panicore mentions, you can just buy some uber-cheap redirect traffic for a few minutes
