In my experience it's quite the opposite for some workloads: Linux FS and process spawning speeds are typically way faster than Windows one (with or without WSL), so much that even when in a VM with dozen of % of overhead, it is still faster than running on Windows for some workloads (just cold open a random man page under WSL, compared to a VM, and you will understand how much Windows lag behind Linux in some areas -- next you can try to build a big program: same result: Windows is really slow) Now this does not render WSL useless; launch time for any random small tool is better with WSL than booting a complete VM, the memory is not partitioned, integration with the Windows Drive FS is slightly better, etc. But tons of use cases are better covered by a VM -- and with a huge margin.

File System and process spawning...I'm not sure what you mean? When working in WSL? or natively in Windows?

Give me a break. After it's actually released and the performance gets better then it is of course going to trump running a whole VM and to suggest otherwise is just FUD, IMO.

  RS1 is mostly frozen. I think Win10 is quite good, and that WSL is quite good given its age, and will be extremely useful for a lot of things. Still, if you try some workloads, WSL is way slower than a Linux VM. I don't expect it to change for the release. I don't even expect it to change for the 2 years to come. Sill, of course, I could be wrong. But even so; I insist: WSL is actually quite impressive.
