same number of gems on both slices?
% gem list | wc -l
are you sure that gem and ruby match?

This profile doesn’t find a single gem, try:
ruby -rubygems -e ‘p Gem.source_index.size’
In fact, it didn’t try to even load any gems. There’s no call to
Gem::SourceIndex#load_gems_in and no calls to
Gem::SourceIndex#load_specification.
Even if you don’t have any gems installed and have nuked your repo,
you should call #load_gems_in.
There seems to be something wrong with this RubyGems.
Slow VM:
ruby -r profile -e ‘require “rubygems”’
% cumulative self self total
time seconds seconds calls ms/call ms/call name
1.49 5.97 0.14 14 10.00 397.86
Gem::SourceIndex#load_specification
This profile found 14 gems, but has one fewer require.
Also, is RUBYOPT or RUBYLIB set?
Also:
$ ruby -r profile -e ‘require “rubygems”’
% cumulative self self total
time seconds seconds calls ms/call ms/call name
33.33 0.05 0.05 57 0.88 9.12 Kernel.require
I ran something like this:
$ rm -rf ~/tmp/gems; GEM_HOME=~/tmp/gems GEM_PATH=~/tmp/gems ruby -r
profile -e ‘require “rubygems”’
% cumulative self self total
time seconds seconds calls ms/call ms/call name
27.59 0.08 0.08 54 1.48 14.81 Kernel.require
You seem to have called require more times than me, can you diff
against:
$ ruby -e ‘require “rubygems”; puts $LOADED_FEATURES.sort.join("\n")’
