[Freeswitch-users] CPU for FS boxes. High freq.? or more cores? or more cache?

Thu Jan 25 21:10:00 UTC 2018

Hi Abaci

We tend to use Intel-based servers in production and my experience is inline with others. More cores trumps faster cores.

For a recent upgrade, I created a load generator on an AMD Ryzen 5 1600 (3.6 GHz). I was comfortably bridging over 4000 parallel calls. It was a simple bridging application and no transcoding, but media was proxied.

I’ve actually quite enjoyed the newer AMD CPUs; I’ve had good performance with my virtualisation testing too.

Good luck with your testing,

Tristan
