I did that, and it found and did nothing -- I suspect it ran when I
re-booted -- it did take a while to reboot.
However, this is pretty consistently what I'm getting now:
$ time python -c "import numpy"
real 0m0.728s
user 0m0.327s
sys 0m0.398s
Which is apparently pretty slow. Robert gets:
$ time python -c "import numpy"
python -c "import numpy" 0.18s user 0.46s system 88% cpu 0.716 total
Is that on a similar machine??? Are you running Universal binaries?
Would that make any difference? I wouldn't think so, I'm just grasping
at straws here.
This is a Dual 1.8GHz G5 desktop, running OS-X 10.4.11, Python 2.5.2
(python.org build), numpy 1.1.1 (from binary on sourceforge)
I just tried this on a colleague's machine that is identical, and got
about 0.4 seconds "real" -- so faster than mine, but still slow.
This still feels blazingly fast to me, as I was getting something like
7+ seconds!
thanks for all the help,
-Chris
