# More Info here: http://unicorn.bogomips.org/Unicorn/OobGC.html
# require 'unicorn/oob_gc'
# GC every two requests that hit /expensive/foo or /more_expensive/foo
# in your app.  By default, this will GC once every 5 requests
# for all endpoints in your app
# Example:
#  use Unicorn::OobGC, 2, %r{\A/(?:admin/work_items/ast|admin/work_items/lp)}

# Use at least one worker per core if you're on a dedicated server,
# more will usually help for _short_ waits on databases/caches.
