Increase PACKETS_PER_BUFFER to 65536
1) This mainly increase PACKETS_PER_BUFFER to 65536 to reduce the
frequency of TCP client acks.
2) Also kills TCP_BUFF_SIZE and define each buffer size in a
more intuitive way.
3) Free more unused memory to prevent being killed by oom-killer
after enlarged PACKETS_PER_BUFFER.
4) Increase client's select() timeout to 20 secs, since we encountered
timeout due to CPU busy in the same BM but with 20 VMs.
Tested this PS in a 10 VM node env, and it can multicast a 2.7G
file to 10 VMs in 6 minutes, while unicast needs 30+ minutes.
