Oh my god... are you guys still mentarbating over this crap?
First off... compare apples to apples. ruby 1.9 loads rubygems by =
default.
4605 % time for i in {0..100}; do ruby19 -e ''; done
real 0m3.089s
user 0m2.066s
sys 0m0.663s

real 0m1.414s
user 0m0.771s
sys 0m0.438s
Second. Be glad you're not running python or anything on the jvm =
(compare `time gem list` vs `time jgem list`):
4604 % time for i in {0..100}; do python -c ''; done
real 0m14.186s
user 0m11.212s
sys 0m1.717s
Third... WHO CARES?!?!? This is all bullshit comparisons for bullshit =
reasons. You don't use ruby for speed of runtime. You use it because =
you'll be done AND have profiled and optimized the bottlenecks before =
they're done. You use it because it's a great language to develop in. =
You use it to GET STUFF DONE and AVOID THESE THREADS.
