Hi everyone,
I found and tried two optimization hacks; however, I don't feel too
comfortable with them. Therefore I would appreciate your opinion:
- Caching proc objects, i.e.
class Symbol
def to_proc
@to_proc ||= Proc.new { |*args| args.shift.__send__(self, *args) }
end
end
- and disabling the GC during an action:
around_filter do |controller, action|
GC.disable
begin
action.call
ensure
GC.enable
GC.start
end
end
On some of our machines and with some requests they boost performance
by as much as 50%. however, as I don't know if I shuld feel ssave with
them I would like to hear your opinions.
