Hello there, I have a bit problem while majoring the squid performance now. There are many TIME_WAIT connections left on the squid port by using high performance http client machine, and then the next connection can not connect the squid. The client machine has capability to send up to 10,000 req/s. I tried to change Linux machine's some parameters as bellow. sysctl -w net.ipv4.tcp_tw_recycle=1 sysctl -w net.ipv4.tcp_max_tw_buckets=50000 sysctl -w net.ipv4.tcp_fin_timeout=1 Silly changed to be better, but nothing big changes. Does anyone know how to purge the TIME_WAIT connections immediately? The machine running the squid has 16GB memory, the fastest CPU and running on 64 bit mode. Thanks a lot, Seiji Kobayashi
