Dual Xeon + Slack = weak web server?

masterross · 01-13-2006, 06:18 AM

hi,

i'm running
Slackware 10.2 Linux server 2.6.15 (gcc version 3.3.6) #1 SMP Fri Jan 6 02:28:13 EET 2006 i686
2Gig of RAM, 2 IDE HDDs

the only thing that i use this box is for my vbulletin forum
but the loads are really high - 40-50 even peack on 70
i've just moved from AMD 2200+ server where loads wre max 15
check my top:

I read somewhere about disabling Hyperthreading on Xeons can improve performance.

This mainly refered to heavily used Database servers where the shared processor cache was being thrashed by one virtual proc thus stalling the other.

I suppose it could be worth a try.

i've just saw that ONLY 1 CPU is running !!!

Code:

how it's possible i see 2 PCUs:

i've just reboot wth:
lilo -R Linux noapic
and now CPU usage is fliped:

Hello

From what I have seen, processes seem to move from one CPU to another often.

masterross · 01-15-2006, 09:22 AM

finnaly i get them work !

Code:

top - 17:16:30 up 12 min,  1 user,  load average: 1.81, 1.42, 0.79

Swap:  2097136k total,        0k used,  2097136k free,   413024k cached

i put in lilo:

Code:

append="acpismp=force noapic acpi=ht"

acpismp=force - i used to force using of HT but after some tests i saw that is not necessary

noapic - disable this error:

Code:

kernel: ..MP-BIOS bug: 8254 timer not connected to IO-APIC

and at the last but not at the last place - acpi=ht
THIS IS THE MAGIC WORD !!!

i'm not sure what exactly acpi=ht does.. but it works...
if anyone can tell me what acpi=ht does will be great

BR,
Ross
