Subject: rainbows slower?
Date: Fri, 8 Jun 2012 09:04:48 -0700 [thread overview]
Message-ID: <CAKN4AWvqRyxTMOVNjc5bGzrkOKGZJ6TsTwBuYu_ZekXaeqT9ag@mail.gmail.com> (raw)
Hi,
I have a "hello world" sinatra app, benchmark:
ab -n 1000 -c 100 http://$mysite/
Total transferred: 264000 bytes
HTML transferred: 13000 bytes
Requests per second: 308.76 [#/sec] (mean)
Time per request: 323.871 [ms] (mean)
Time per request: 3.239 [ms] (mean, across all concurrent requests)
If I put rainbows in front of it, I get:
Total transferred: 272000 bytes
HTML transferred: 13000 bytes
Requests per second: 61.62 [#/sec] (mean)
Time per request: 1622.745 [ms] (mean)
Time per request: 16.227 [ms] (mean, across all concurrent requests)
rainbow config looks like:
worker_processes 7 # i'm on an 8 core system
Rainbows! do
use :EventMachine # sinatra app using "thin"
worker_connections 1024
end
config.ru looks like:
require './webserver'
run Sinatra::Application
ruby version is: ruby 1.9.3p194
I tried telling apachebench to use keepalives (-k) and that slowed
rainbows down more (and sped up the straight sinatra app).
I have changed worker_processes and worker_connections with no effect.
I added keepalive_timeout 0 to the Rainbows! block with no effect.
any idea why rainbows is slower? I'd like to take advantage of all my cores.
thanks,
Joe
