Really slow to install on USB and subsequent Boot

[seshu]

Hi there, I'm a first time Qubes user and I did an install (v4.0) to a USB 3.0 stick last weekend. IT took about 5 hours?! Is that normal? I realized I had VT-d on my i7-6700k diabled in the bios during the install but I fixed that and then tried to boot from the USB and it would take 25 minutes to boot up?!

What am I missing? I do have about 6 SATA drives on the desktop, but I have 32gb or RAM and the USB stick is 128gb, and the CPU is i7-6700k so it is a fast cpu.

Appreciate any advice! Thanks in advance.

Have you benchmarked the flash drive? Sadly, just because it's USB 3 doesn't mean it's fast :(

I seem to recall there was a bug in Xen when 4.0 first shipped that
caused USB3 devices to run at USB2 speed. Try updating dom0 and your
templates and see if that helps. Not sure the bug affected the
installer, but maybe 4.0.1 will work better when it comes out.

Good point I haven't done that. I've been doing some research and even though my i7-6700k is supposed to support VT-d, and VT-x, with EPT, some tests I ran indicate it may not support. Not sure if that is something that would cause such a poor performance?

Thanks for the info. Being new to Qubes, I'm not sure how to update dom0? can you point me to any thread or help on how that is to be done?

Thanks!
