Hello,
ublk zero copy is observed to improve big chunk(64KB+) sequential IO performance a
lot, such as, IOPS of ublk-loop over tmpfs is increased by 1~2X[1], Jens also observed
that IOPS of ublk-qcow2 can be increased by ~1X[2]. Meantime it saves memory bandwidth.
So this is one important performance improvement.
So far there are three proposal:
looks like there is no dedicated session. Could we still have a
discussion in a free slot, if possible?
Sure, and we can invite Pavel to the talk too if he is in this lsfmm.
I'd love to go but regretfully can't make it
