hi mike,
you and the rest of ian's group did a noble job by optimizing and saving
some resources between the radius daemon and the external program by making
a gateway or bridge by using of your radius helper daemon. regarding to onie
case and he is using a mysql database as a backend, assuming he is using
your radius helper daemon, the bottleneck that i saw is between the external
program and the mysql daemon. every time a external program communicate to
mysql daemon, it will open a mysql database file, queries it and close the
database file when its done. the time to open and close a database file is a
big factor in terms of performance especially when your metric is request
per second. :-> maybe this is a another big challenge to ian's group to
create a helper between the external program and the mysql or any database
server as what your group did between the radius daemon and the external
program.
