I went to rough a similar exercise when I was playing around with packet ordering example.
Here’s a rough formula I came up with.
Comments are welcomed
Total pool size = Sum of the following numbers
-RX queue size x number of ports
-TX queue size x number of ports
-Size of ring x number of rings
-MAX_pkt_burstsize x number of threads since each does a read of that size
