Quoting Troy Wilson [off-list ref]:

Do you have any stats from the hardware that could show
retransmits etc;
I'll gather netstat -s after runs with and without TSO enabled.
Anything else you'd like to see?
Troy, this is pointing out the obvious, but make sure
you have the before stats as well :)...

have you tested this with zero copy as well (sendfile)
Yes. My webserver is Apache 2.0.36, which uses sendfile for
anything
over 8k in size. But, iirc, Apache sends the http headers using
writev.
SpecWeb99 doesnt execute the path that might benefit the
most from this patch - sendmsg() of large files - large writes
going down..
thanks,
