I upgraded to Insider Release 15055 recently and noticed that pandoc within WSL was performing very slowly. I am not sure if this affects many other applications under WSL since this is the main one I use.
I did an uninstall and re-install of WSL just to make sure nothing was causing problem.
Here are the results from a fresh WSL with pandoc 1.19.2.1 deb package installed, comparing it to the Windows binary

UPDATE: I've attached the strace output for this as well. pandoc-strace.txt
UPDATE: This is not specific to release 15055 since I found the same issue on my desktop which is not on the fast ring. I also installed the pandoc package from Ubuntu xenial and the issue does not occur with it. So something about the binary from this current deb version is causing issues.
Would there by any further profiling that would help to isolate what's going on? I don't have exact numbers from previous releases but I definitely didn't experience run times on the order of 20 seconds.
