High number of context switches

[Thomas Söderberg]

Hello

Have installed zfs on ubuntu 10.04 server (dell r710) running just one
zfs on a dedicated device 300Gb 15k

Writing to the zfs pool are causing very high level of context
switches and thereby causing slow performance.

This is not anything I experienced with zfs on solaris so it must have
something to do with the linux implementation.

Regards,

Thomas
