WSL 1 is mind boggling slow, ESPECIALLY when it comes to disk access. 
Updates on a basic Ubuntu instance (no gui, just a couple of small 
utilities installed on top of the base WSL image) take an absurdly long 
time.

Reason being 2 main factors. Windows disk access tends to be slow and 
wonky compared to native Linux. (Or anything else really.) So anything 
that has to go through Windows has to deal with that. The other issue is 
that WSL 1 isn't virtualization, it's really more of an emulation layer. 
It's not even technically Linux as no Linux kernel code is running. The 
emulation layer, which isn't even 100% complete, adds a fair amount of 
overhead.

WSL 2 is due to hit mainstream with the next release of Win 10 (2004). 
That's a different animal altogether. That will be running an actual, 
upgradable copy of the Linux kernel, with full system call 
compatibility. It is in fact, full virtualization, you need computer 
hardware capable of running Hyper-V. You can even install and run stuff 
like the Linux version of Docker and FUSE. Third party benchmarks show 
pretty impressive speed gains in 2 over 1, some that even come close to 
a bare metal install in terms of speed.

I still prefer bare metal installs, but this is a pretty good way to 
actually be able to get stuff done in Windows, especially if you're 
required to do so.
