> WSL's backing filesystem (NTFS) completely runs like ass. It's dire. 10x the latency on everything at least compared to Linux running natively on the same hardware. This is because all small writes end up in MFT contention and the entire of Unixy type things are based on lots of small writes.

that is hard to emphasize more than it is - doing C++ dev on WSL is complete garbage, lots of small write on compile, SLLLOOOOOOWWWWWWWW...
