[dm-devel] performance considerations with IO schedulers and DM multipathing

[Paul Cote]

Hi,
 
Is there any advantage to one specific IO scheduler (below) that may
improve IO performance / throughput when running with a round-robin
failover policy? Has anyone done testing with this ... and willing to
share results?
 
thanks,
Paul
