Hi, I use netperf to test the performance of small tcp package, with TCP_NODELAY set :
netperf -H 129.9.7.164 -l 100 -- -m 512 -D Among the packages I got by tcpdump, there is not only small packages, also lost of big ones (skb->len=65160). IP 129.9.7.186.60840 > 129.9.7.164.34607: tcp 65160 IP 129.9.7.164.34607 > 129.9.7.186.60840: tcp 0 IP 129.9.7.164.34607 > 129.9.7.186.60840: tcp 0 IP 129.9.7.164.34607 > 129.9.7.186.60840: tcp 0 IP 129.9.7.186.60840 > 129.9.7.164.34607: tcp 65160 IP 129.9.7.164.34607 > 129.9.7.186.60840: tcp 0 IP 129.9.7.164.34607 > 129.9.7.186.60840: tcp 0 IP 129.9.7.164.34607 > 129.9.7.186.60840: tcp 0 IP 129.9.7.186.60840 > 129.9.7.164.34607: tcp 80 IP 129.9.7.186.60840 > 129.9.7.164.34607: tcp 512 IP 129.9.7.186.60840 > 129.9.7.164.34607: tcp 512 SO, how to test small tcp packages? Including TCP_NODELAY, What else should be set? Thanks! -- Best Wishes!
