Hi,
We are testing write performance of md raid5 with SSD array and we are
hitting limit which I understand is caused by writes being handled in
single thread (md0_raid5 process is eating 100% of 1 CPU core when the
test is running). I understood that there is some work in progress which
should make write handling multi-threaded. I'd like to ask about the
status of this work, is it still in progress or planned?
Regards,
Prema
