[#28561] Ruby::DL vs Ruby::FFI — Aston <blackapache512-ticket@...>

Ruby.DL and FFI libraries are great for programmers like me who are not internet programmers, but are more interested in scientific and number processing etc.

[ruby-core:29007] [Feature #3010] slow require gems in ruby 1.9.1

From: Roger Pack <redmine@...>
Date: 2010-03-25 21:47:32 UTC
List: ruby-core #29007
Issue #3010 has been updated by Roger Pack.


It appears that you can avoid the use of gem prelude by doing something like

require 'rubygems'
gem 'xxx'
require 'xxx'

If you run it with 1.9.x with "--disable-gems" thusly, for me it gives 

1.8.6: 1.0s
1.9.1 --disable-gems: 1.1s
1.9.1 normal: 4s

Hmm.
Appears that the slowdown (here at least) is by calls to Kernel#require taking quite awhile.

On Linux for me, however, 1.8.6 takes 0.3s, 1.9.2 (with gem prelude) takes 0.5s, so not as bad of a difference.
