Has the 4.1 as well as 4.1.1, because I did test on both, release added additional overhead to the creation of a dvm?
I have identical dvm's for Firefox on 4.0 and 4.1 and on 4.1 it takes almost, in the region of 0.5 - 0.75 seconds almost, **double** the time for a new dvm to be ready for usage, 18 seconds vs 36 (both rounded for convenience).
That is quite a hefty difference. Is there any explanation for this behavior?
I have the similar as yours, but the time of one of my qubes cannot be open because of light VM error that I got, which is error 135. The time doubling effect is just to place for the computer took way too long on some occasional reasons to go for it. Anyways, it’s just the distro issue from Debian.

How can it be a distro problem from Debian? Or Fedora? The same version of either on either 4.0 or 4.1 should be the same. Or not?
The problem lies within your computer processing speed and the numbers of qubes you has opened and active in one minute; This will significantly increases the opening time. As a result, it doubles the time of opening and activating the qubes to be online.

I didn't spell that out down to the letter but to make matters worse when i tested the creation time of the dvm on 4.0 the system was in fact far more busy compared to my test on 4.1. on 4.1 only the bare minimum was booted, sys-net, sys-firewall, sys-usb, sys-whonix, and that is it. On any regular day there are about 18 VMs running at any given time. So definitely the measured time was not influenced by how busy, or lack of, my system was.
It might be the speed in which to generate a new random number for this disposableVM and taking the file for a long time due to the size of that one file.

This really is quite an annoyance, my system has slowed down quite a bit in the area of dvm's and i use them intensively. Can someone help me understand this problem? Where must i scratch under the bonnet to determine why dvm creation takes so much longer on my 4.1 install compared to my 4.0 install. I have two identical SSD's (make, model, etc) one installed with 4.0 and the other with 4.1. The SSD i used for the 4.1 install has much less mileage on so general wear of the SSD should effect my 4.1 install less.

It is not only dvm creation that is slow any VM boot time has increased significantly.
There can be multiple reasons for a slower 4.1 experience. Known ones are:
1. CPU runs at ~800 MHz or so [1]
2. You're a file pool user. File pools were serialized in 4.1, likely dropping their performance by ~30-50%. [2]
3. Possibly further issues in 4.1 [2].

I have read through 7075 but i am still distilling the info. It does sound like i may be affected by the same issue.
What makes this debacle so uncomfortable is the fact that time spent waiting is cumulative and at the end of the day it adds up to a lot of time wasted.
Anyway it seems that just a few users are affected. Others report 8s VM startup performance or less (see forum).
I will try and make time to run some additional tests with the help of the scripts you provided in your detailed 7075 bug report. Would you mind sending me your updated scripts?
And i really appreciate the efforts that you have already put into resolving this issue. You are really helping your community tremendously. High five.
This is the first time i am suffering from Qubes performance issues and i have to say it is quite frustrating. If 4.0 wasn't going EOL next month i would continue using 4.0 for now.
