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.
