| |
I recently upgraded my desktop from 2.4.28 to 2.6.10. Even under moderate memory pressure kswapd regularly eats almost all available cpu time whenever there is a little more IO throughput, like copying large files. The system is extremely sluggish during this. The system load goes up to 7.5 or more.
This is a Pentium3-866 with 768MB RAM, 2x1GB swap partitions, vanilla 2.6.10. The strange behaviour starts at about 200 MB of swap in use. 2.4.28 masters the same workload without any problems.
vmstat: procs -----------memory---------- r b swpd free buff cache 6 1 428012 4868 33236 347184 ---swap-- -----io---- --system-- ----cpu---- si so bi bo in cs us sy id wa 10 7 147 120 108 111 19 10 68 3
Is there anything I can do to track this down?
