Did someone say virtual is slow?

Let's compare the performance of a real environment and a virtual one (running MacOS and Linux in a Parallels VM).

This comparison is kinda synthetic in sense that the sample was doing purely computational stuff, where hardware makes virtualization transparent. The real applications do lots of system calls, and that's where virtualization overhead can be noticed, since many syscalls or driver calls have to be intercepted (and emulated) by the hypervisor.

I'm gonna say that the biggest flaw of that test is that it's purely CPU Load, the moment, you need to access HDDs or any other virtual devices, you will generate some overhead to do so, and it will consume a non negligible part of the host resources to do so.

I just got my first MacBook and I tried Windows in parallels. AMAZING! It’s mesmerizing how I can use MacOS and windows in time same time on the same machine. Using MacOS on one display, and Windows on another screen(only when I need windows). Also Parallels it’s very nice because of how well it works and integrates with MacOS.

Exactly what I wanted to see comparing metal vs virtual. How about comparing UTM(qemu) vs UTM(apple virtual) vs virtual box vs parallels vs vmware.
And comparing to emulation(amd64) as well

Amazing test Alex!! Never disappointing to watch your videos

[jacklwipa]

Another awesome test from Alex!
I love how you much info you give on the real world developer performance we get from  silicon. Whilst everyone talks about video editing, you talk about the developer aspect of it. I love your content more than I can put into words.

Didn’t realise you could run Linux VM’s natively on ARM yet, that’s mega!

I was waiting for Schwarzenegger v2.0 🤩

Article about MacBooks being used as a desktop with lid closed. My intel one being used as a desktop most of the time got the display replaced because of video circuits hanging the machine when connecting a second external display which led me to believe some thermal effects of having the lid closed that long of a time. Any better on m1/2 MacBooks?

I’m impressed by Linux !
Great test, really entertaining 👍🏻😊

Hey Alex,
I've been struggling testing this I find that Compiling code on Windows in a VM (Parallels) is much slower than the Volterra Dev box. I thought it was because I was using a 8GB MacBook Air M1 so just purchased a new M2 Pro 14" with 32 GB and its the same. On a small project I am finding that on average the Volterra Box will compile from the command line (msbuild -t:Rebuild -m) in approx. 1.5seconds but the Mac takes like 3.5-4seconds. So I am seeing for Windows Development workflow using Windows in Parallels twice as slow as the Volterra box infact my old Surface Laptop 3 is faster than the MacBook. Any thoughts have you tested compile times rather than CPU performance? Thanks Sean.

How do Apple Silicon Macs do running IntelX86/AMD64 workloads in a QEMU VM?
This is an issue for running docker containers that have not been recompiled for ARM or Apple Silicon.
Does Parallels have Intel emulation option (perhaps using Rosetta)?

Cool video! Can you do a comparison between Parallels and UTM/QEMU?

[connorzittrauer]

Would be interesting to benchmarks between different linux distros.

The other day I booted up two clean VMs of Ubuntu and Xubuntu and was surprised to find that regular Ubuntu was actually faster and snappier.

The only thing that might be different are processes that are io bound. There can be software in the VM implementation between the hardware and the virtual machine.

That Schwarzenegger machine is really creative idea u built for these laptop tests

[kusulas]

Hi Alex, which is the code python do you have used?, for test here :)

Can parallels 19 run big sur vm in m1 macbook running ventura?

[ronensuperexplainer]

Throughput performance is the same or better in a VM than in the host, but latency performance is much better in the host. That includes system calls, CPU scheduling, interrupts.

How much RAM does the same program uses between both OS? In mac experience every time I use my Debian 11 WorkStation instead of my MBP I think Linux uses less RAM, then when I have to work with a Java BackEnd, 3 Node JS FrontEnt at the same time I have to use the Linux WS.
