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. |

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

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.

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 |
