So it the 2.6 Kernel faster than the 2.4 Kernel?

I recall reading in this forum about the multitasking timeslice being reduced by a factor of 10 (?) and it was slowing down mprime.

Perhaps more importantly is it easy to upgrade?

The ease of upgrade really depends on the linux distribution you are running, if they support the 2.6 kernel then you should be pretty straightforward.

I use Gentoo and upgrading was easy, I've a friend who upgraded a Fedora box (using the 2.6 RPM) without any problems.

Here is an article that shows some perfomance differences between 2.4 and 2.6: http://www.infoworld.com/infoworld/a...FElinux_2.html

But that doesn't tell you how mprime will perform though...

I just compiled a 2.6.4 kernel on an Athlon 1200 box running Slackware 9.0. The kernel size was about 30% bigger than the old 2.4 default kernel and the speed looked to be about 2% slower. It's even more disappointing because the 2.6 kernel was running at a lower screen resolution.

The speed difference is the same for my P4. Mprime benchmark averages about 2% lower with an otherwise idle 2.6.4 kernel than with a 2.4.25 kernel.

As far as the memory usage, I found that even though the 2.6.4 kernel image on disk is about 20% larger, it actually reserves slightly less memory once running compared to a 2.4.25 kernel.

Here are some of my stats. Machine is a hyperthreading P4, kernel 2.6.4 was compiled with all features present in 2.4.25, plus the anticipatory IO scheduler which is not in 2.4.25.

Code:
                                   2.4.25    2.6.4
--------------------------------------------------------------
bzImage file size:                   939K    1118K
Total kernel memory after boot:     8116K    7908K
mprime 384K FFT iteration time:     12.7ms   13.0ms
mprime 1024K FFT iteration time:    33.7ms   34.3ms
mprime 2048K FFT iteration time:    72.9ms   74.7ms
