tcp tuning tcp_reordering

[:--:]cat /proc/sys/net/ipv4/tcp_reordering
The tcp_reordering variable tells the kernel how much a TCP packet may be reordered in a stream without assuming that the packet was lost somewhere on the way. If the packet is assumed lost, the TCP stack will automatically go back into a slow start since it believes packets may have been lost due to congestion somewhere. The TCP stack will also fall back from using the FACK algorithm for this specific host in the future.

This variable takes an integer variable and is per default set to 3. This should in general be a good value and you should not touch it. If this value is lowered, it may result in bad network performance, especially if packets often get reordered in connections.
