After migration, it is significantly slow.

hi, guys,
thanks for first!
I migrated an open source Switchmap from old BSD to a window XP 2003 server. The program is writen in perl. it is a cisco switchmap software. it took 3.5 hours to complete. but in the new mechine it takes about 9.5 hours to complete.
The only thing i changed in the program is / and \ for path, since the windows uses differently than unix.

What is the problem?
thanks,

Han,

Hi there Han,

I think you're probably looking at the difference in efficiencies between the two operating systems.

Did you really need to change the slashes?

Checkout perldoc perlport for hints on portable scripts.

Possibly a difference in the way you are forking or using disk access. Did you move to a newer/faster machine or did you just reload your bsd machine with 2k3?

Travs, the new machine is windows and much fast.

Hi Han

I don't use Activestate Perl very often and don't have it installed on this computer to test. But I think that perldoc is a command installed with Perl.

Alternatively, you can get the doco all over the web, eg,

http://theoryx5.uwinnipeg.ca/CPAN/perl/pod/perlport.html

A bit of light reading for you but I don't think it's your problem. Still, might be interesting.

Enjoy

You might add some logging to the script and see where it is spending most of it's time and see if there are some improvements that can be made.
