Sbt build times substantially slower on Windows vs Ubuntu.

steps

Using Windows 10 vs Ubuntu 23.10
sbt version is 1.10.0

SBT_OPTS are
-Xmx16G
-Xss1000M

Reproducing would be a case of taking two machines with similar specs but with the corresponding OS, then comparing the compilation times of a project with a non-trivial build time

problem

This is a problem that has affected everyone at our company using windows and sbt. The crux of the issue is that, when compiling the same projects in windows vs linux, the compilation time is 3-4 times longer, extending 15 minute full multi-project rebuild processes into hour long wait times. While some of us have swapped onto linux with work machines, this is a less than ideal solution for those working from home.

The expectation would be that there isn't a major difference between the two.
