Description Ferdinand Gassauer 2003-04-24 10:09:22 UTC

Version:            (using KDE 3.1.1)
Compiler:          gcc version 2.95.2 19991024 (release)
OS:          Linux (i686) release 2.2.19

Hi!
IMHO the processes preparing the print output should run with nice.

If KDE is running on a server it considerably slows down the the overall performance if the print process (gs or ps2pdf) a running with high priority.

I found the exec:/gs command and just wanted to suggest to prepend "nice" to all of the commands.
Do not know if this works on all platforms

On a single user box it will not do much harm except it accelaretes other things which are not blocked by gs any more and on a multiuser system all processes/users  would benefit.

in my case samba didn't respond any more in time.

Not feasible for KDE to do. If someone desires this, he should set up his system individually to make cupsd run with a different "nice" level.

Changing this would only trigger myriads of other wishes, in attempts to renice other daemons and processes in favor of KDE.

If a user does not need to print, he should disable cupsd altogether.

Comment 2 Ferdinand Gassauer 2007-02-06 17:08:31 UTC

I was not talking about cups - I do not think that cups daemon and processes are a burden.

I was talking about the (KDE) appication generating the ps or pdf file which create sometimes (graphics) a very high CPU load slowing down or prohibiting to do other things.

IMHO this can/could be controlled by KDE programms.
