Hi, all
I am trying to make a dual P4-Xeon box (P4DCE, Intel 869) work optimally. After some search in list archives, I have found this points:
- You need ACPI, and boot with acpismp=force, to have hyperthreading (see 4 cpus) - To balance interrupts, a patch from Ingo is needed - To balance timers, one other patch was needed, but this in included in 2.4.19-pre8 (do not know since which pre is there)
I tried to boot with acpismp=force, but then performance was dog slow, I could count lines scrolling on a rxvt. I checked mtrr and look like working. Box has 1Gb of ram, so kernel is using CONFIG_HIGHMEM4G=y. Kernel is the standard highmem Mandrake kernel in 8.2 (2.4.18-6mdkenterprise) that is mainly a plain 2.4.18 with some .19-pre1 fixes.
Any correction ? Any known problem in 2.4.18 about this issue that has bee corrected in pres for 19 ?
Any idea about the performance loss ?
TIA
