Hi all,
I'm working on TCP segmentation Offload and I'm using
Linux -2.6.14 kernel for this. I'm getting about a 6x increase in
sending by turning off TCP segmentation offload. But When I turn on
the TSO my performance is getting degraded. But when I switched back
to Linux
2.6.9 kernel I'm getting 16Mbps more when TSO is enabled.
Is there any TSO patch for linux-2.6.14.
Thanks In Advance
Anand

Which hardware and what is the network connection?
It turns out that older versions of TSO were violating internet
congestion control
and not counting packets properly.
