frankly it is not wise to disable nagle, and the solution i proposed
(using netfilter extension) is really too tedious - the added overhead
may slow down the processing, even though disabling nagle aims to
improve latencies.   but modern network card is so fast, that the
bottleneck is not at the network card side, but more likely in the
network gateway, or router side - so u are definitely not going to see
improvement in spite of all the troubles.
