Open source Projects for Performance/Load/Stress Testing
I am a Software Testing Enthusiast and i have mostly worked on Functional Testing(Manual). I am interested in performance testing and i have worked on a very small project where i used LoadRunner. I would love to be a part of an open source team which works on Performance Testing. As a lot of experienced guys are part of this community can you please tell where to look and how to master the art of performance testing. P.S. I think this question might be considered as Off Topic but when i searched the internet for open source performance testing projects i mostly got results related to tools. I dont know how to proceed. Your help will be appreciated. UPDATE: Thanks everyone for your response. All of your answers have helped a lot.
