Sure if there would be significant improvements that accomplish what
you claim above then that would be certainly worthwhile. Come up with
patches like that please.
The patch appears to make some work loads twice as fast ('make clean'),
and it had a reasonable speedup to the 'make -j12'. What do you
consider 'significant'?
I'm willing to do some other network-related benchmarks with his patch if
that would give it better chance of being accepted. (I end up running
with SLUB debug quite a bit on big, heavy, workloads...so any speedup
in that would be a big help for us...)
Thanks,
Ben
