I just tried out v0.5.8beta
on a MacBook running OS X version 10.5.8,
connected to 1 bitcoind v0.8rc1 peer at riker.plan99.net (courtesy of Mike Hearn).
My internet connection is running at 100 Mbit/s.

One wallet with 20 addresses, reloading the whole blockchain (220867 blocks) from the genesis block took less than 11 minutes.
That equals 335 blocks/second.

Congratulations and a big THANK YOU to all bloom filter developers!
