Description

We're noticing that VMs on SSDs take about half the time to sync content on_demand. For Fedora (46K package, url: http://fedora.osuosl.org/linux/releases/23/Everything/x86_64/os/ ) this is about 20 minutes for an SSD VM and 45+ minutes for a VM on a HDD. Is there any thing we can do to speed up lazy sync for machines running on HDDs?

Example HDD sync:
