I m currently using freeradius-server 2.1.7. when i try to authenticate it takes abt 400 millisec to authenticate. i use peap-mschapv2 for authentication. So in 1 sec the number of devices i can authenticate is jus 4 to 5.

No. Multiple authentications can be done in parallel.

so wat to do? should i modify anything in the freeradius code to increase the authentication rate.

For EAP, the only way to increase performance is to buy a faster machine. Nearly all of the CPU time is spent doing cryptographic calculations. See raddb/certs/README, the PERFORMANCE section. Alan DeKok.
