Currently not. We'll work on improving DispVM performance, but after final 4.0 release. Some ideas include: - having PVHv2 really working (it will cut stubdomain and bootloader out of boot process - about 1-2s improvement) - pre-starting a DispVM so it sits there ready for use[2] - this have noticeable memory impact, but similar to 3.2 - copy of the savefile is stored in dom0 RAM As for qrexec timeouts, this is unrelated issue[1], which we have some (hopefully sufficient) fix - it will land in testing repo today.

It certainly did something that made DVM's start really quickly. Definitely faster thaw a normal VM. I always assumed it took a snapshot after booting, but I could be wrong. I would very much like to know what it did. Whatever it did, it certainly made the experience of using DVM's much nicer, and the question is if something similar is available in 4.0? -- You received this message because you are subscribed to the Google Groups "qubes-devel" group.
