CMGS 最新进展，找了一台物理机，8核，8Gb CentOS，客户端：i5 2.4Mhz, 8Gb
内核参数：
fs.file-max = 999999
net.ipv4.tcp_rmem = 4096 4096 16777216
net.ipv4.tcp_wmem = 4096 4096 16777216
net.ipv4.tcp_tw_reuse = 1
net.ipv4.tcp_fin_timeout = 15
net.core.rmem_max = 16777216
net.core.wmem_max = 16777216
net.core.netdev_max_backlog = 4096
net.core.somaxconn = 4096
net.ipv4.tcp_max_syn_backlog = 4096
net.ipv4.tcp_syncookies = 1
net.ipv4.tcp_max_tw_buckets = 360000
net.ipv4.tcp_no_metrics_save = 1
net.ipv4.tcp_syn_retries = 2
net.ipv4.tcp_synack_retries = 2
[root@sz-monitor ~]# ulimit -n
1000000
[root@sz-monitor ~]# ulimit -Sn
1000000
[root@sz-monitor ~]# ulimit -Hn
1000000
并发10000，ab -n 5000000 -c 10000
