Runnng python 2.2 on HP-UX, I get intermittant slow startup.
Sometimes python starts up in a small fraction of a second, and
sometimes takes 3-5 seconds. This applies to any script I run, or
just typing 'python' at the prompt.
I also observed something similar on Linux.
Any ideas what would cause *intermittant* slow startup?

Caching? Is it a long time between invocations that it takes a long
time to start up?

It is quite intermittant without much of a pattern I can see. One
thing that is definitely true is that if I start up python several
times in a row one right after the other, some can be slow and some
fast. I just observed it start fast twice, then start slow. I don't
remember if it ever does the other way around but I think it does.

I've noticed that on Windows a lot, but not on Linux or Solaris.

I double-checked that and asked the sysadmin to check if the python
build was using any network source. I do have AFS and NFS drives
mounted on this machine, but I'm not reading any python code from them
as nearly as I can tell. PYTHONPATH points only to local disk.
