on linux: only one cpu in use?

| it's debian etch with the stock 2.6.18 kernel. performance is ok, beside 
| the fact that the load climbs up when the cache is about 40-50 % full 
| (with a 517GB cache file); below 40 % the load stays below 3, but after 
| that level it rises to over 7 and even 10 at peak times. the response 
| times are still good, though.

Is this with the mmap or the malloc backend?

| we just installed irqbalance to see if this makes a difference. after 
| some minutes (without restarting varnish), the picture according to top 
| to "top" is, that 3 out of 4 core do most of the I/O:

Unsure why this happens.
