Hi All,
I have two mac boxes... on my G5 machine, all pythons
are slow to start:
time python2.4 -c "pass"
real 0m2.726s
time /usr/bin/python -c "pass"
real 0m2.909s
user 0m0.023s
sys 0m2.719s
But on my G4 laptop I get a real time of 0.09-0.15s
which is much more acceptable, but this is a slower
machine. I've been looking at ktrace to see if I can
figure out what is causing this. Can anyone give a
recommendation on how to get a little more info out of
the trace? I am guessing that it is some particular
package causing a problem.
Thanks,
-kurt
