Hi Peter,

We found performance of our pool about 25-30% better than we were getting
with the MINA leader follower pool.

However this may be in part due to the fact that we separated the filter
into two cases - one for reads and one for writes.

I'll take a look at the issue and comment if I can see anything different
in what we're doing.

Robert

Aside from how you had your ThreadPoolFilter push write events into
the event pool, how did you find performance? I just did a sample
implementation that uses the TPE, and the performance for the
regression test shows it to be slower than the Leader-Follower pool..
Any thoughts on how to improve TPE performance would be appreciated..
