How long do database writes take?
insert in acccouting db takes ~ 10ms
delete from accouting db takes ~ 25ms
How many writes can you do
simultaneously?
As many as simultaneous query I guess...
How many packets/s does the server get?
For the authtentication database I have about 10 authentication queries/s but regularly reaches 30/s when problems on BAS or DSLAM outcome (max value since last year is ~80/s).
Generally, you should have as many SQL sockets as threads.
Thread like in start_servers and max_servers in radiusd.conf?
Any more,
and they won't be used. Any less, and the threads might starve.

The LDAP && SQL modules really need to move to a dynamic connection
pool. It would be much easier for the administrators.
Indeed
