Are you using streams?  A while back I experimented with matrix multiplication using streams
and they can be very slow:

https://stackoverflow.com/questions/35037893/java-8-stream-matrix-multiplication-10x-slower-than-for-loop

So I would think that Java has a lot of performance tuning and optimization it could do in
this space.

Cheers,

or if anyone might know what could cause that given that the release notes  don’t directly
point to anything.
