Description

Hi,
We have a big cluster of 12 servers each server has around 20 osd to store data and 5 ssd for journal. We have different users they are connected to ceph cluster using iscsi.Now the problem is when we do windows copy from local server to ceph writing has no issue but when we do block(chunks of big file) copy instead of just regular windows copy then the writing speed is so less. We checked the network there is no issue from switch side. We have 10GbE ports. We changed the jumbo size to 9000. There are no specific issues we find. Please guide us in some direction to fix this issue asap. Please ask for any more information needed. It should be fixed soon as users are having very hard time.

Thank you.
