Actually, Lovely Systems uses PGStorage because it is faster for them.

It would be interesting where PGS is faster than filestorage. Ok, I just tried made a simple benchmark for testing write performance. I created a Plone site and then created a copy using copy/paste within the ZMI.
(AMD Dualcore 2.6 GHz, Postgres 7.4.7 running on dedicated DB server):

Copy&Paste using Filestorage: 3-4 seconds
Copy&Paste using PGStorage: 30-40 seconds

I doubt that one could optimize the write performance using PGStorage
significantly. DCOracleStorage had a similar bad performance compared to Filestorage (10 times slower as far as I can remember).
