I´m not sure.
I´ve seen and used the PHP Session management in high performance environments before and it works just fine. I think the more interesting question is how we use it.
I mean how often do we read and write data and how much data do we store in the session. I´m sure we can optimize a lot here.

By the way: Klaas and I discussed yesterday a strange bug. In the WebDAV http response header are two
Set-Cookie: PHPSESSID entries with different session IDs.
There is an interesting bug in our session management somewhere.
