Hello,

after performance trouble I had with 9.3.2, I've tried to migrate to
9.4.0b1, 64bit version.

Results are:

average load before: 75-80%
average load after: 25-30%

upd packets loss before: thousands per second in spikes
upd packets loss after: <2000 since reboot (3 days)

queryperf test before: ~30000 qps
queryperf test after: ~45000 qps

RedHat Enterprise Linux 4 ES, SunFire X4100, 6GB RAM, 2x Opteron 252
processors

packet loss estimated by: watch 'netstat -s |grep "packet receive error"'

Seems like quite radical change to me ;-) Good work.
