Using httperf, I decided to run a few load tests against a simple "Hello World" type app - in the latest Web Velocity build I have installed. Now, based on my previous uses of httperf, I have limitations on the number of open sockets I can use at once - it seems to tap out around 40 requests/second on the client (i.e., the Mac I'm using to run httperf). Web Velocity didn't seem to even notice the load at that level, so if anyone has better tools to recommend, I'd love to hear about them. Anyway - I used this command against the app

httperf --verbose --hog --timeout=10 --client=0/1 --server=mickey.local --port=7777
--uri=/HelloWorld/Hello --rate=40 --send-buffer=4096 --recv-buffer=16384 --num-conns=1000
--num-calls=1

httperf: maximum number of open descriptors = 1024
reply-rate = 40.0

reply-rate = 40.0

I ran the tests multiple times to be sure, but it seems that Web Velocity can handle whatever I can throw at it locally quite nicely
