Rubyinstaller devel - Aug 2009 - 1.9 gem env is far slower than on 1.8?

Currently when I run "gem env" on a windows machine

with 1.8.6 it takes [~80 gems installed]

real    0m0.360s

with 1.9.1 [~80 gems]

real    0m1.610s

with 1.9.2 [~40 gems]

real    0m1.140s

[all with 1.3.5 installed]

Not so for Linux--1.9.2 seems slightly faster than 1.8.6 for its gem list.

Anybody have any inkling as to what''s going on here?
Thanks!

FWIW, I''ve noticed my 1.9.1 gem commands are noticeably slower than my
1.8.6 commands.

Same thing when I''m run rspec.

For example, when running a spec for a patch to the treetop cmd line compiler I
submitted, I was seeing ~20 secs on 1.9.1 vs ~12 secs on 1.8.6 on my Win test
box.  While there were plenty of Kernel.system and Kernel.open calls, I was
surprised at the delta.  Haven''t tried it yet on my XUbuntu 9.04
system.

All the IO operations has been noticeably slower with 1.9 on Windows,
perhaps related to Unicode layer and additional processing needs to
perform over all the gemspec files.
