Indeed, this might be related to the hypervisor/IO system rather than Ganeti itself. Which Hypervisor do you use? And which storage type? For highly intensive machines, especially if they don't need much redundancy (eg. git you can just clone to a second machine) perhaps you want to do "plain" rather than drbd.
