Performance: files or SQL?

[Mike Jackson]

On my personal server, I'm running SA 3.0.4 with the user prefs, Bayes, and 
AWL in a MySQL database (mostly because it would be "cooler" that way). On 
my employer's server, I'm running the same SA version, but with file-based 
DBs and user prefs. We're going to be rolling out doing filtering for all 
our mailboxes (several hundred) as opposed to opt-in (as we're doing it now 
on about 20 accounts). I know I could do benchmarks myself, but I wanted to 
get your impressions if there's a performance improvement using SQL for 
storage (user prefs, Bayes, AWL) rather than files. Thanks.
