we succesfully tested a coupple of ARM64 Supermicro with 128 cores’ Ampere Altra Max cpu and ConnectX-6DX cards.
We reaced 220gbps and 18.5Mpps using speedtest tcp with random data, in that case the cpu were close to the maxium, but it is normal with such high number of packets and traffic.
But when we moved the box in a production we saw a very high kernel cpu usage with very small traffic, 3.5gbps and 1Mpps.
We tested 7.20b2 and 7.19.1, the beta2 could be bettere because it uses all 128 cores instead of 64 about the 7.19.1 but in the production test the cpu usage was higher in 7.20b2 then in 7.19.1; the means to me that there isn’t a specific optimizzation about the high number of cores in arm64 version of router os.
Does someone elsa have a similar experience?
