Performance problem on SunOS 5.8

[kielhd]

Hi NG,
I am running a script doing some calculations on a SunOS box. It takes
about 11hrs to finish.
When running the same script on WinNT, it takes only 7min!
I was very surprised about WinNT being app. 100 times faster then
SunOS and compared the results. The results are the same, so the
script is working well on both machines.
I am using perl v5.8.0 and the module Net::Netmask on both machines.

Could somebody please explain this to me or - even better - give me a
hint of how to improve the performance on SunOS.

that makes little sense.

Invoking the devine ESP function of Perl......

Are you doing any DNS lookups at all?

If not, how do you seriously expect anyone to have an idea without showing
any code or snippet.

Greetings from rainy Philadelphia, PA.

I'm not aware of any inherent speed differences between perl
implementations on Windows versus Unix. You'll have to post more
specific information (like, the specific code that is showing such a vast
speed difference).

Adding to the other requests, you're not giving any info on what
hardware you're on. I believe I could find a WinNT environment that
runs at a fraction of the speed of the WinNT environment you have,
and perhaps also a WinNT environment twice as fast as you have.
Of course, _if_ these results were obtained on the same hardware
(doesn't seem so), it's a different issue.
