Message-ID: <551AD6AE.4030607@cra.cz> (raw)

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
