| |
I am running 2.3.18ac8 on an ABit BP6 with dual Celeron 300s and 128MB RAM. When running a uniprocessor kernel, the system performance is as expected, but when running an SMP kernel, the system is generally slow and clunky. My RC5 keyrates are half (or less) than they are when the uniprocessor kernel is running. A quick look at the procinfo output reveals the following:
irq 0: 6507260 timer irq 6: 3 irq 1: 25880 keyboard irq 10: 277422 NE2000 irq 2: 0 cascade [4] irq 13: 1 fpu irq 4: 128804 serial irq 14: 229244 ide0 irq 5: 44716209 soundblaster irq 15: 3 ide1
Doesn't the interrupt count for IRQ5 look a little high in comparison with the timer count? Could this be an indication as to what's causing the poor performance?
When the system is sitting idle in GNOME/Enlightenment with a couple of xterms running, the load is in the 3-5 range which seems abnormal as well.
Any assistance is appreciated. I can provide any more additional information as necessary.
Mike.
