Re: lower cpu priority to perl scripts

Tamer,

Thank you very much for the reply. I googled around for the proper syntax of your suggestion as well as which config file I need to edit with it, but I came up with a big fat 0. Can you provide a few more details for me? Apologies in advance, I am a newbie with apache2

You can always start your scripts with [re]nice() syscall to lower
your process (perl script in this case) priority.

Subject: [users@httpd] lower cpu priority to perl scripts

I'd like to adjust the priority of /usr/bin/perl such that it will always run with very low priority. The PC that I'm using isn't very powerful. I'm running rrdweather on it and when a user hits the weather.cgi about 10 processes of perl scripts run,
which totally throttles foreground applications until they finish.

How can I assign /usr/bin/perl to always run with a really low CPU priority (a really high nice value) for any script it executes? Is this an apache2 setting or...?
