Hello!
Thank you for great work. We have few heavy loaded LVS system with a lot of
connections.
I'll test patch as soon as possible.
Best regards,

Subject: WLC Slow start for 2.6.x kernel

I took Simon's patch and made an attempt to forward-port onto 2.6 and latest
3.0.x (working mainly with "ipvs-next" and "net-next" trees):
https://github.com/kwilczynski/miscellaneous/blob/master/ipvs-thundering-herd-2.6.patch
https://github.com/kwilczynski/miscellaneous/blob/master/ipvs-thundering-herd-3.0.patch
Making sure that it holds water in my test environment / set-up.
Unfortunately, I do not have the ability to test this under a real life load
and/or in a network / system that was suffering from the problem that this
patch is trying to address. I other words, my notebook solely is not enough to
see real benefit of the slow-start introduced by the patch, since it will reach
limit of its capacity long before I am able to create enough congestion to spot
the difference in a statistically significant manner.
Therefore, would you help me Aleksey and test it for me? :-) I am asking for
your assistance, since you requested the forward-port in the first place,
therefore you are probably the person whom will benefit from it the most.
Hopefully, everything will work as it says on the tin, and if so, then we can
start working on merging this with upstream kernel and exposing ability to
toggle this functionality on-demand via /proc and/or /sys entries per algorithm.
Thanks for help in advance! :)
