Hi Philipp, > 1st FLOWR query on collection: ~700ms > 2nd+ identical query same collection: just ~200ms !
If I get it right, you ran the same query, and the second run was faster than the first run? This will mostly be the case, no matter which database you are testing. Once a query has been run, the requested data will be available in disk or main memory caches. Moreover, Java will also get faster and faster due to Just-In-Time compilation. If you want to do some serious benchmarking, you should use the client/server architecture of BaseX and start your real test after "warming up" your server instance (i.e., running all kinds of queries).
