New Load Testing Tool for Roller After reading Hani's comments about Freeroller's abysmal performance (which I agree does suck), I sent the following e-mail to Novosoft: 

Any chance you'd like to donate a copy of your software to the Roller 
Weblogger open-source project (http://rollerweblogger.org).  We could
really use a stress-test tool like yours.  We're using it at my day 
job and it works great.

Their software is a load and stress testing tool that a co-worker discovered and it works awesome. At my day job, we know that if 17 users click on the same button at the precise same time, then Hibernate (or maybe it's Oracle) will throw a deadlocking error. We doubt that we'll ever get 17 concurrent users, so it's not an issue for us, but it's nice to know.

Anyway, their software is $250, which is a little steep for any open source project. However, I was delighted to find that they obliged my e-mail and sent me a license this morning!

Dear Matt, 

Thank you for your feedback and your warm words regarding our product!
We have decided to grant you registration key for our product WAPT 2.0.

Sweet! Now I just have to find time to create these tests, or maybe one of the other Roller Developers has time? Posted in Roller at Jul 31 2003, 07:21:57 AM MDT 6 Comments

That would be perfect for testing the connection/request fix in the 097 branch.

Is there a tag on that branch for benchmarking before/after changes?

There will be, just as soon as I am done ;-)

Anyone can use DiselTest for FREE, a great stress testing tool (Part of basicPortal/Jasic, and linked on basicPortal.com downloads page, just FYI). .V

I checked in the 097 changes and tagged them with ROLLER_0975_PRE1. I've been load testing with JMeter, but I'd love to see some results from a "real" load tester.

Just 17 people can cause your site to deadlock? For a project I'm working on, we are considering using Hibernate (right now we use our own rolled classes) with an Oracle backend. However, our traffice is fairly large and 17 concurrent users (if not many more) is very likely. Have you been able to determine if this is an hibernate issue? This would really make us re-think some of our planning.
