ADAM does not cache searches (or execution plans) like SQL does. However, it
caches DB pages. So, if your database is smaller than RAM, then once you
stress it for a while, all pages will get cached in memory, and it will
become faster, because there will be no physical I/O.

If you want a realistic stress test, then create a realistic dataset and run
it on realistic hardware.
