> Hi Ales,

Are you? Possibilities of dedicating a standalone machine to freeradius,
paravirtualization of disk access in vmware environments, offloading syslog
to other servers, PARTITION or SHARDING, and you have not mentioned
innodb_file_per_table=1 which was made default only in recent versions.

Have also a look at this, https://launchpad.net/mysql-tuning-primer (I have
an idea there is a similar, more recent one, cannot find it atm).

Of course, as Alan says, all the best strategies start for not using the DB
for certain situations in the first place.

If using AD for authentication, I would have also a look at the recent
developments of authenticating directly against SAMBA >= 4.2.x

Regards
