siege can help you accomplish that goal. It allows you to specify a time to run and it gives you some flexibility with scheduling requests. Let's say you wanted to run approximately 12,000 hits in an hour. You could do something like this: siege -c 250 -t1h -d 15 http://www.haha.com/whoohoo http://www.joedog.org/index/siege-home Cheers, Jeff ________________________________________ From: Krish, Sailesh [skrishnamur1@xxxxxxxxxxxxx] Sent: Tuesday, July 21, 2009 2:31 PM To: 'users@xxxxxxxxxxxxxxxx' Subject: Stress testing apache 2.2 with ab Hi, I would like to stress test an apache web server using ab. How do I get it to send a certain number of requests per hour? Do we need to use the –t option. The man page is not very clear. Basically Im trying to simulate ccurrent usage and see the behaviour when I add some more load.The current usage statistics on the web server are as below: . Avg Max Hits per Hour 7272 26925 Hits per Day 174532 323706 Files per Day 109310 202612 Pages per Day 123434 228832 Sites per Day 10 21 Visits per Day 507 969 KBytes per Day 22448481 42197378 Thanks for the help. --------------------------------------------------------------------- The official User-To-User support forum of the Apache HTTP Server Project.
