Unfortunately no, I can't. We made measurements during a
consulting job I did for another company, and it was made by
them, not me, *plus* I wasn't smart enough to save a copy of
the numbers :-/

Anyway, the biggest problem they had was stability, their ZODB
grows and shrinks insickening speeds, and Data.fs would break
for some reasons I don't remember anymore, and OracleFS solved
that. I'll try to convince them to write a report to the list.
