| 37 sockets does not seem much. Maybe you have very large buffers.
| You may want to check /proc/sys/net/ipv4/tcp_rmem and tcp_wmem,
| and maybe reduce the values there.

$ cat /proc/sys/net/ipv4/tcp_rmem
4096    87380   174760

$ cat /proc/sys/net/ipv4/tcp_wmem
4096    16384   131072

What are these values?
