Though it may be moot by now, I just ran some tests of my own with
patch. This was on a dual 2.4 GHz Xeon booted with a UP kernel,
running iperf over an e1000 at a 1500 byte MTU. I measured idle CPU
running a process which sits in a gettimeofday() loop. Numbers are
utilization, all turned out +/- 1%.
No TSO: 86.6%
Old TSO: 61.0%
New TSO: 88.5%
Yeah, TSO Reloaded really stinks. :-)
Try the "Super TSO" patch I just posted instead.
Interesting timing. :)
With the new patch I'm getting 78.0%.
