 The more CPU threads you have the better your FFmpeg encode to FFV1 will perform. To calculate the CPU threads for your server you can multiply the Threads x Cores x Sockets. So for our configuration this would be 2 (threads) x 16 (sockets) x 2 (cores) = 64. To retrieve these figures we would use Linux's ```lscpu```.
