some new interesting results with 2.5.42:

http://spunk.dnsalias.org/latencytest/2.5.42/2x256.html

overall much worse, *but* greatly reduced latency peaks (max. 6 ms) as
compared to 2.5.41:

http://spunk.dnsalias.org/latencytest/2.5.41/2x256.html

here the peaks easily reach 13 ms.
i'm not really sure what to make of this....
can someone explain ?

andrew, it seems part of your mm patch was merged - is there an updated
patch around that will add the missing hunks ?

best,

jörn
