Impressive. I get the following timings for Eclipse RC2, gij 3.4 (CVS
HEAD, verifier disabled), starting up and using the mouse to select the
exit item as soon as possible (it then takes a couple of seconds to
"Save the workspace"):
Complete fresh start (two splash screens):
real 3m41.889s
user 3m28.310s
sys 0m3.320s
Second startup (one splash screen):
real 2m44.068s
user 2m33.670s
sys 0m2.430s
This is on an Athlon XP 1.4Ghz with 768MB.
The bottleneck seems to be class loading and exception handling.

Nah. Proprietary implementations don't count. I assume your timings are
with Mono on Wine. None of that proprietary MS stuff I hope :)
Cheers,
