My experience is that CS works *a lot better* than SS on SMP machines
(with my apps in particular).

We have an app (kind of a small ERP), 1Gb DB and at least 200
concurrent connections (reporting/updates) with FB running on a
Windows 2003 with 4 Xeon processors. We tryed 1st SS (our usual
install) 'tied' to 1 processor and than moved to CS wich performed *a
lot* better.

Even with smaller apps (few records (200MB db) and with about 10 to 20
concurrent users only) we have experienced better performances using
CS over SS on machines with 2 or 4 processors.
