Hi all! I recently got GPU passthrough working on one of my VMs and I'm delighted to say that everything appears to be working as it should, with one minor exception. I'm noticing some serious slowness in the IO/hard disk department. Sometimes the guest machine appears to be fine. Other times, task manager reports that the disk is at 100% utilization and the IO plummets. I'm using FreeNAS as my storage solution with essentially a stripe of mirrors. That's a 12 disk stripe. All matching. Even though it's just a software RAID, I believe I should see some very decent numbers with that kind of working room. I should note that via an SMB share I can transfer into my FreeNAS box from my laptop at roughly 100MBps, rock solid. The NAS is available to the Proxmox node via NFS. I haven't enabled jumbo frames on my network. Should I? I've heard of "hugepages" mentioned before on other forums when this topic has arisen. Can someone give me the 411 on what those are and whether or not I should enable them? The host is running Proxmox 5.0 Beta 2 with the latest updates. The Win 10 VM specs are as follows with a little commentary: 8 CPU cores, 1 socket 8GB RAM (I've heard some people say to try using less RAM, but that kinda defeats the purpose of the machine in my case) virtio balloon driver in use (I've heard this sometimes causes problems too.) virtio driver for disk raw disk image w/ write through cache 1 passed through GPU 1 passed through USB port Help y'all! I want this baby to purr!
