Hello everyone,
First of all thank you for building such a great product!
Unfortunately I encounter extremely slow queries using a basex instance. My xml files are distributed over 256 databases (00-ff) with roughly 250MB each. All share a structure similar to [3]. I executed OPTIMIZE ALL for all databases, see [4]. [5] shows the info index output. The linux server which is running the basex instance shows great amounts of io. I replicated the data to my local desktop and see the same amount of high io usage across all database files. For example: [data\81\tbl.basex, data\81\txt.basex, ..., etc]
Querying a single database is fast and the info output window shows the following [2], but a query across all dbs just stalls and does not return a result in a reasonable time.
Could somebody give me a hint how to speed things up?
regards, Björn

Example query:
