Hello, I have a 8 core x86_64 machine that has 2 Intel 82574L NICs using the e1000 driver.
Problem: During a spoofed SYN flooding attack (800 Mbits, ~300K packets/sec) the ksoftirqd became the bottleneck of the system. The daemon ran on a single core using 100% cpu. We had about 40% packet loss. Google tells me, the problem is "NAPI". How can I disable NAPI? Thanks a lot Sandy ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
