Freeradius V.3.2.0 performance issue

Hello, i have tested freeradius V.3.0.22 and freeradius V.3.2.0 with the same configuration on centos 7 using redis as database backend and i have seen that v.3.0.22 is more performant than v.3.2.0, for a test of 25k acct/sec runned for 1hour with V.3.0.22 i didn't registered any packet lost however with V.3.2.0 i have more than 600K packet lost, i confirm that i have the same configuration and the two versions are running on the same machine with 16VCPU and 16GB RAM with localhost redis database. Thanks Bassem
