I was looking around today for some means to load test my scripts, I happened upon this website:  http://loadimpact.com/

It’s free services were alright, but up to 50 users just won’t put my scripts through they’re paces!  I’ve looked into trying something called ApacheBench before, but had trouble.  It’s something you can only access through SSH, and when in there I kept receiving “-bash: ab: command not found” errors.  Not fun!

The problem was I wasn’t in the right directory.  I found out you can search for ApacheBench but running “find / -name ab” (without quotes)  then you would include the directory when running ApacheBench “/dir/ab -n 100 http://yourdomain.com"
