Subject: optmize librbd for iops
Date: Mon, 12 Nov 2012 14:50:14 +0100 [thread overview]
Message-ID: <50A0FE96.9030708@profihost.ag> (raw)
Hello list,
are there any plans to optimize librbd for iops? Right now i'm able to
get 50.000 iop/s via iscsi and 100.000 iop/s using multipathing with iscsi.
With librbd i'm stuck to around 18.000iops. As this scales with more
hosts but not with more disks in a vm. It must be limited by rbd
implementation in kvm / librbd.
Greets,
Stefan
