<div dir="ltr">Thanks for feedback Krzysztof and Alexandre. Below are the info:<div><br></div><div>I am using 1x 500GB WD HDD. I can add another one if that helps - something like: WD5001AALS. Would that help? Where do you read the IOPS? and what is a good number of IOPS today?</div>
<div><br></div><div>For VM I am using LOCAL QCOW2 - not sure how virtio drives work.</div><div><br></div><div>Hoping following info help you tell me if I am hitting a controller bottleneck (meaning I can't help it) or if it is an HDD problem:</div>
