I am preparing to go live with an app, and was wondering if someone can give me some insight on my benchmarks. How do they compare, what system level tweaks can I make to improve them etc.
My setup is the following:
- m1.large amazon ec2 instance, running Ubuntu 11.04 Natty.
- Nginx as a reversed proxy for web requests. These requests are servered over unix sockets to a pool of unicorn workers that serve up a ruby (1.9.2) app (Sinatra as the framework)
When running apache bench as follows ab -n 10000 -c 10 http://localhost/ I get negligible memory consumption, and higher cpu spikes. I see about 75-80% cpu usage
top results:
Cpu(s): 43.1%us, 20.9%sy, 0.0%ni, 21.5%id, 1.0%wa, 0.0%hi, 2.4%si, 11.1%st
And my benchmark results are as follows:
