You may want to use PostgreSQL or MySQL, rather than SQLite:
https://trac.edgewall.org/wiki/TracPerformance#Database
Trac 1.4 with Jinja2 should give the best performance.
I don't have experience with Apache on Windows, but I've read there can be
performance problems.

Concurrent request performance is pretty good on Linux with Apache and
PostgreSQL or MySQL, in my experience.
