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
Alan asked me to so some further testing. I wrote a small script
creating 100 Documents within one transaction (both in CMF and Plone)
and I calculated the transaction time (not included the overhead
for creating the instances)...the numbers are pretty much the self-speaking:
CMF Plone
PGStorage 10-12 secs 15-18 secs
Filestorage 0.3-0.4 secs 0.4-0.6 secs
