Hello,

I've measured 2.2.1 on my Baget (r3k, 25 MHz) by lmbech and see that
context switching latency was increased. 2.2.1 latency is greater by 2
times for 2p/0K and almost the same for 16p/16K. The difference
decreased monotonically, so in the middle, i.e. for 8p/16K the
difference in 1.5 times greater. I didn't make further investigations
yet and before I'll do them, I'm very interesting in any suggestions
and/or experince with other MIPS boxes.

Regards,
Gleb.
