Running this explain on windows box, but production on linux both 8.0.1

The MSSQL is beating me out for some reason on this query.

The linux box is much more powerful, I may have to increase the cache, but I am pretty sure its not an issue yet.

It has 8 gig internal memory any recommendation on the cache size to use?
