[ruby-core:37818] [Ruby 1.9 - Bug #4962] come back gem_prelude!
Issue #4962 has been updated by Eric Hodel.
I have found some unnecessary work in rubygems and am running benchmarks to see what effect delaying them until they're necessary have on `make benchmark`.
----------------------------------------
Bug #4962: come back gem_prelude!
http://redmine.ruby-lang.org/issues/4962
Author: Yusuke Endoh
Status: Open
Priority: Normal
Assignee: Eric Hodel
Category: lib
Target version: 1.9.3
ruby -v: -
Hello, rubygems developers
Kosaki-san noticed that 1.9.3 is slower than 1.9.2 on many benchmarks.
http://www.atdot.net/sp/view/5qunnl
I investigated and found that the cause is the lack of gem_prelude.rb.
Loading rubygems seems to create many objects and keep the references
to them. See below:
$ ruby -ve 'GC.start; p ObjectSpace.count_objects[:TOTAL]'
ruby 1.9.2p180 (2011-02-18 revision 30909) [i686-linux]
9821
$ ./ruby -ve 'GC.start; p ObjectSpace.count_objects[:TOTAL]'
ruby 1.9.3dev (2011-07-01 trunk 32356) [i686-linux]
19638
$ ./ruby --disable-gems -ve 'GC.start; p ObjectSpace.count_objects[:TOTAL]'
ruby 1.9.3dev (2011-07-01 trunk 32356) [i686-linux]
9821
The number of live objects is proportional to the cost of GC mark phase.
You can actually confirm the performance degradation with the following
benchmark script:
require 'tempfile'
max = 200_000
str = "Hello world! " * 1000
f = Tempfile.new('yarv-benchmark')
f.write str
GC::Profiler.enable
max.times{
f.seek 0
f.read
}
p GC::Profiler.total_time
$ time ruby -v bm_io_file_read.rb
ruby 1.9.2p180 (2011-02-18 revision 30909) [i686-linux]

ruby 1.9.3dev (2011-07-01 trunk 32356) [i686-linux]

user 0m3.716s
sys 0m1.060s
$ time ./ruby --disable-gems -v bm_io_file_read.rb

0.7640390000000309
real 0m4.079s
user 0m2.872s
sys 0m1.192s
The performance degradation can be seen by not only such micro benckmarks,
but also my puzzle solvers :-(
There are some approaches to address the problem:
1. to introduce a generational GC; this is impossible until 2.0 because
it requires modifications to all extension libraries.
2. to diet rubygems; do not create any string, array, hash, and any
object as much as possible, and do not keep the references to them.
3. to restore gem_prelude.rb to delay loading rubygems.
I guess that 3 is a reasonable choice for 1.9.3. But I'm fine with any
solution to fix rubygems if 1.9.3 becomes as fast as 1.9.2 on the
benchmarks.
