hi,
i am testing performance of  my Freeradius using java multi threading and i am facing an issue 

normaaly acounting start procedure taking less then 1000 miliseconds. and this is my requirment

but after some requests free radius takes more then 5000 miliseconds continusly then returns normally...

return code in all requests is 0


Accounting Start process times of some requests...
