[openib-general] Re: [PATCH] IPoIB splitting CQ, increase both send/recv poll NUM_WC & interval

[Shirley Ma]

OK. I am going to split the patch without splitting CQ first.

WC handler is called in the interrupt context, it is a myth
to have bidirectional performance improvement with splitting CQ.
More investigation is needed.

If WC handler can be moved from interrupt context, splitting CQ
is still an approach. Having a seperate thread or NAPI support
can be implemented later.

Thanks
