Re: slow perl script interpretation (syntax check)

You may want to use something like Devel::Trace or perl -d:DProf to see if you can spot where things are slow in the code. Running memcheck and some io bechmark on the system itself might find something, too....in otherwords, you need to dig a lot deeper.

Yes, we even use an "enhanced" trace and debug package of our own but it doesn't seem like a perl error, i.e. all is executing normally when traced as a perl but it's the initial interpretaion/syntax check that's slowing the things on the "new" OSes. I will try to do some io testing but I will be suprised if that's the problem as it happens on different hardware platforms and OSes (FC5, CentOS5 tested for now). Thank you! P.S. I wonder ... could it be glibc issue, as all of the FC5+ are using glibc-2.4 while the older use glibc-2.3	[reply]
