freeradius performance , requests per second

Hi I am using freeradius 1.1.6 on Suse Linux 10 , and mysql for database. My processor is Intel Pentium 4, 3.40 Ghz, RAM is 512 MB and hard disk is 80 GB. On this configuration how many requests , freeraradius can handle per second. Is there any tool which can test the performance of freeradius. Can you please tell me the average number of authentication requests that freeradius can process per second. can it handle 1 lac requests per second. thanks deepak
