Now that Canonical has released Ubuntu 21.10 (Impish Indri) you can use my latest release of ‘isorespin.sh‘ to respin Ubuntu ISOs:
and Lubuntu ISOs:
as well as the other supported flavours but remember to install the additional package 'zstd' before respinning as this release uses a new compression tool.
Please remember to donate if you find my work useful.
Following news of the GRUB2 Secure Boot Bypass 2021 and as a result of Google's security changes on Google Drive together with the first daily build's from Canonical of Ubuntu 21.10 (impish) and point releases for 20.04.3 and 18.04.6 I've updated my ‘isorespin.sh‘ script and respun some ISOs suitable for Intel Atom and Intel Apollo Lake devices.
Note that support for 21.10 (impish) is not finalized as the release is still under development so respinning will be experimental at this stage. However due to a new compression tool being used an additional package 'zstd' will need to be installed prior to attempting any respinning.
Unfortunately interest seems to have declined judging by the lack of donations so please remember to donate if you find this work useful.

I've previously looked at Windows and Linux performance on the NUC11PHKi7C Enthusiast Phantom Canyon which is Intel’s latest NUC 11 flagship product specifically targeting gamers as it includes an NVIDIA RTX 2060 GPU.
One usage aspect I didn't test was virtualization and this brief article looks at the performance running VirtualBox and WSL2 on the NUC11PHKi7C and comparing it to Intel’s previous NUC with a discrete GPU: the NUC 9 Extreme Ghost Canyon.
Hardware Overview
For the NUC 9 Extreme I’ve using a NUC9i7QNX model and I purchased both the NUC11PHKi7C and NUC9i7QNX as barebone devices.
The NUC11PHKi7C has an Intel Core i7-1165G7 Tiger Lake processor which is a quad-core 8-thread 2.80 GHz processor boosting to 4.70 GHz and also includes an NVIDIA N18E-G1-B notebook graphics card which is a GeForce RTX 2060 mobile GPU. I’ve installed a 2TB M.2 2280 NVMe drive from addlink (S70) and 64GB (2 x 32GB) DDR4 3200MHz memory from G.SKILL.
The NUC9i7QNX has an Intel Core i7-9750H Coffee Lake processor which is a hex-core 12-thread 2.60 GHz processor boosting to 4.50 GHz. I've installed a 2TB M.2 2280 NVMe drive from ADATA (XPG 8200 Pro), 64GB (2 x 32GB) of Team Group’s Team Elite DDR4 3200MHz memory and an EVGA GeForce RTX 2060 KO ULTRA GAMING GPU.
Software Overview
On each device I've installed Windows 10 Pro and Ubuntu 20.04 LTS as dual boot. On Windows I've enabled Windows Subsystem for Linux (WSL) version 2 and then installed Ubuntu 20.04 LTS Linux distribution for WSL. Then for each OS I've installed Oracle VM VirtualBox and created VMs of either Windows 10 Enterprise or Ubuntu 20.04 LTS as antithesis to the host OS.
Installation Issues
Whilst there were no instalation problems with the NUC9i7QNX, the NUC11PHKi7C encountered a major issue. Initially for Ubuntu I was using the latest kernel (5.8.0-48-generic). Once Windows 10 Enterprise was installed in VirtualBox I noticed the VM occationally crashing for no apparent reason. However after downloading Passmark Performance Test version 10.1 the installation file refused to run:
I then had slightly more success in downloading and installing Passmark Performance Test version 9.0 however the application then refused to run:
but I did get Passmark Performance Test version 8.0 to both install and run:
however it subsequently crashed the VM.
After many reinstalls and web searching I discoverd that a bug for the crashing issue has already been raised: https://www.virtualbox.org/ticket/20180 and that 'using a Linux kernel 5.4 does not exhibit the problem'. Switching to the 5.4.0-70-generic kernel did indeed solve all the problems including no more crashes and allowed the successful installation and execution of Passmark Performance Test version 10.1.
Virtualization on Windows
For a Windows baseline I ran the CPU tests from Passmark Performance Test natively in Windows:
 |
| NUC9i7QNX |
 |
| NUC11PHKi7C |
and interestingly despite having fewer cores the NUC11PHKi7C's Windows performance was 3% better than on the NUC9i7QNX.
The first virtualization comparison is against running Windows in VirtualBox on Ubuntu where I ran the same CPU tests using the Linux version of Passmark Performance Test:
 |
| NUC9i7QNX |
 |
| NUC11PHKi7C |
and this shows that hardware-wise the NUC11PHKi7C performance was 18% worse than the NUC9i7QNX. Software-wise virtualization on the NUC9i7QNX performed similarly to its native performance at only 1% lower however for the NUC11PHKi7C it was 19% worse.
For an Ubuntu baseline I ran the CPU tests from Passmark Performance Test Linux natively in Ubuntu:
 |
| NUC9i7QNX |
 |
| NUC11PHKi7C |
and this time the NUC9i7QNX Ubuntu performance was 1% better than on the NUC11PHKi7C.
The second virtualization comparison is against running Ubuntu in VirtualBox on Windows:
 |
| NUC9i7QNX |
 |
| NUC11PHKi7C |
which again hardware-wise shows the NUC11PHKi7C performing worse than the NUC9i7QNX but this time by only 12%. Virtualization however is markedly different with the NUC11PHKi7C being 47% worse than running Ubuntu natively and 42% worse for the NUC9i7QNX.
The final virtualization comparison is against WSL2:
 |
| NUC9i7QNX |
 |
| NUC11PHKi7C |
where the NUC11PHKi7C performed 4% better than the NUC9i7QNX hardware-wise. It was also the best for Ubuntu virtualisation with only a loss of 1% for the NUC11PHKi7C and a 6% loss for the NUC9i7QNX. It should also be pointed out that all of the results can be affected by test run margin of error.
The full results are summarised below:
Conclusion
Although this is very limited testing it suggests that from a hardware perspective VirtualBox on the 6-core 12-thread NUC9i7QNX performs better than on the 4-core 8-thread NUC11PHKi7C even though the native performance is similar. Virtualbox on Windows is much worse than on Ubuntu however the real winner is the performance of running Ubuntu under WSL2 as it is comparable to the native performance. Also of note is that Ubuntu performance is slightly better than Windows performance.
