Finding correct max_servers limit for accounting purposes

Hello, I've got stub perl accounting function: sub accounting { return RLM_MODULE_OK; } So there is no slow code. My accounting traffic (In: 2.5 MiB/s and Out: 328KiB/s): [cid:78faf210-0420-47a0-8a82-b54222996377] When first portion of traffic hits server it creates max number of servers. It doesn't matter what number 32, 128 or even 600 so 'max_servers' doesn't seem to make much difference. Here last peak is 600 threads. [cid:0c6bebf9-7ab8-4efd-9834-84710dbd94a8] Should I ever worry about regularly reaching the 'max_servers' number of threads if after creating number of threads goes down or mayne C module will work faster?
