That's right, it's executed for every log message.

I never noticed any performance problem. I just counted the radius
accounting log messages (generated by this script on one server) we have
per day: it's about 700 000. Max per second is around 60.

On this server (with two multi-core CPUs) we have 8 radiator instances
running (load balancing with iptables).

But I agree, it would be better to have the possibility to log
accounting messages to syslog one per line from inside radiator. :)
