You can expect a 3-20% performance increase even in good situations
only.

I don't know what the actual problem is, but if you have a high system
time, then maybe the kernel does polling when acessing your printer port,
which often costs a lot of cpu time.

[Gimp-user] Speeding up printing ...

[Dave selby]

Hello,

I run a system with ...
Gimp 1.2.3, Debian Woody, 700MHz PIII, Epson Stylus C60, Gimp-print driver
My machine struggles when I print high resolution images, the main 
system culprits, from "top" are ...

"print" ... while gimp is processing the image ready for printing &
"epson" ... while printing.
Both float around 80%-95% of CPU time, If I run any other apps the 
printer starts pausing etc ...

Since Debian compiles for a i386 & I have a PIII I have re-compiled 
Gimp, cupsys-driver-gimpprint & libgimpprint1. To my supprise this has 
made no difference.

After ensuring that my processor is set to PIII in the kernel, I deleted 
the packages then ...

apt-get build-dep x
apt-get source  --build
dpkg -i .deb (generated from the previous command)
Has anyone any suggestions ?
Dave
