Hi.
I have a HPE bladechassies with BL460C's in it, with Intel 82599 10 GB dual port nic's in them. Running PVE with lvm on iscsi multipath connected luns
I got the Spurious native interrupt! in the syslogs, and I was lurking around google to fins anything on this.
I found someone issuing ethtool -C <iface> rx-usecs 0 and the syslog entries disappeared, so I decided to try it. Not only did the syslog entries go away, but the NIC speed was vastly increased.
My question here is, how much overhead for the CPU can I expect? Is there a better value for the NIC in question than 0, which still gives me decent performance?
The cpus in this case, are 24 x Intel(R) Xeon(R) Gold 6128 CPU @ 3.40GHz (2 Sockets)
Best regards
