Sony has released an upgraded client for the PS3. Check out Noam Rimon’s (he’s the lead developer at Sony) post:
Starting today a new version of Folding is available.
This version is a minor fix to the previous 1.3 version and adds a
better tuned algorithm that handles peak performance hours of
Folding@home network, by acting differently to certain network errors
if those occur.
It is recommended that you update to the new version
by quitting the application and restarting it. Your current WU will not
be damaged in any way, in-fact Folding will continue from the exact
point you have stopped it.
Please also check the official Sony Folding site here: http://www.scei.co.jp/folding/en/update.html
can already see a stabilized network activity for the last 5 days. With
the new update we are certain that the network will continue to be
stable for good.
At this point I would like to thank people again
for being patient and continue to donate to our project while Stanford
& Sony was working on the fix.

The upgrade should significantly improve the networking performance.
