Enable more TCP connections

Base performance test: 

ab2 -c 1000 -n 1000 http://test
netstat -napt | grep TIME_WAIT | wc

Tutorials:

Faster TIME_WAIT: 

echo "1" > /proc/sys/net/ipv4/tcp_tw_recycle
echo "3" > /proc/sys/net/ipv4/tcp_fin_timeout
 
ab2 -c 1000 -n 1000 http://test
netstat -napt | grep TIME_WAIT | wc

More simultaneous connections: 

ulimit -HSn 4096
 
ab2 -c 4000 -n 4000 http://test
netstat -napt | grep TIME_WAIT | wc
