Measure your system performance with the attached script and find the bottleneck.

If its a third party application as your post SEEMS to indicate, check with the application vendor.

Ashan,

netisr is a user-space kernel helper daemon. You will see that its PPID = 0 as is the case with all kernel proc that run in user space.

netisr is used to service interrupts from incoming data packets. All packets, addressed to the broadcast address, MAC address, or multicast address, will cause netsir to become active. These can be IP packets, or non-IP packets, e.g. PC protocols, broadcast storms, etc.

If netisr is using high % CPU most often you will need to trace network with a Sniffer device, or host-based tools e.g. nettl / netfmt, tcpdump, etc., to find root cause.

ITRC Doc KBRC00001272 has detailed instructions on the usage of nett/netfmt.

Hope this helps,
