[ovirt-users] Slow upload via oVirt Manager

Hi! I am trying to upload some rather large disk images via oVirt Web Manager, but I am getting rather slow speeds. Network is 1Gbps between my pc and oVirt node via which I am uploading, but I am getting around 200Mbps transfer speed. Last time when I was uploading was when I had version 4.4 of oVirt and I haven't had that problem then. Now I am using latest version. Any steps how to troubleshoot this?
