FT status and macvlan performance problems

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi Michael,

sorry for the late follow-up, I'd like to discuss and issue regarding your FT 
patches sent by you. We have tested both Benjamin and your patches, and found 
some performance problems. With our QCA9558/988x (using ath10k) based Access 
points, enabling macvlans on top of bridges result in an performance drop of 
30-40%. 

We have investigated the reason, and it seems like enabling promiscous mode is 
causing this problem. We have seen that Benjamins version of using a raw 
socket on the bridge [1] can be used without enabling promiscous mode and 
keeping the higher performance. However, we when using macvlan, promiscous 
mode seems to always be enabled implicitly.

So far, I have not seen your patch [2] merged and it's marked deferred in 
patchwork [3]. Are you still working on the patch? Or is it in some queue 
which I didn't find, or superseded somehow? Would you consider reworking it to 
be usable without macvlans?

Thank you!
     Simon
