I just upgraded to the new Windows May update which now has WSL 2 (a very lightweight, Hyper V VM running full Linux). I essentially now want to move all my development over to Linux. But I would like to test if there are any regressions in performance when running Julia on the VM compared with the native binary.
What are some of your favorite snippets of code to run benchmarks?
From the non Julia benchmarks Iāve seen, wsl2 sometimes performs on par with a regular Ubuntu install. So I understand it to be a big improvement over the first attempt.
The most relevant benchmarks are always your own programs, so Iād probably start there. Otherwise, you could run the benchmarks from the Julia homepage.
The general consensus is that the performance of WSL2 is on par with a native install (given the Type 1 hypervisor), but only if you stay within the VHD and the linux FS. As soon as you start reading/writing to /mnt/c/ (i.e. to the Windows FS), things slow down tremendously
I would like to see these benchmarks (some or all, at least some multi-threaded too, i.e. where load is close to 100% on more than one of the four), but note itās expected to get better numbers, e.g. I do roughly 2x on my Linux box (some programs there are faster with lower opt settings, I was meaning to point out, and NOT asking for threads):

$ hyperfine '~/julia-1.6.0-DEV-8f512f3f6d/bin/julia -O0 --cpu-target=core2 --startup-file=no pidigits.jl 10000 >/dev/null'
Benchmark #1: ~/julia-1.6.0-DEV-8f512f3f6d/bin/julia -O0 --cpu-target=core2 --startup-file=no pidigits.jl 10000 >/dev/null
Time (mean Ā± Ļ): 1.292 s Ā± 0.054 s [User: 1.669 s, System: 0.501 s]
Range (min ā¦ max): 1.196 s ā¦ 1.366 s 10 runs
And please time āfirst-plotā, in another discourse thread, where I showed this recently, someone said this doesnāt work on Windows:
$ sudo apt-get install gnuplot
$ time ~/julia-1.5-ea669c3d3e/bin/julia -O1 --compile=min --startup-file=no -e "using Gaston; display(plot(rand(10)))"
real 0m0,691s # without display 0m0,400s, and also try other settings.
user 0m0,768s
sys 0m0,542s
File intensive operations like git clone, npm install, apt update, apt upgrade, and more are all be noticeably faster with WSL 2. [ā¦] WSL 2 run up to 20x faster compared to WSL 1
WSL 2 is a virtual machine, but in their words ānot like any VM youāve seen beforeā. They utilize a very minimal HyperV toolset to run the Linux kernel.
Iām not sure how helpful this thread is or possibly outdated:
