Hi Athanasios,
Did you experience slow queries ? Are you sure to use all the index features ? Are these queries operational ones (direct access on a key value) or analytics ?
I never experienced slow queries, even on huge xml corpus (patent registrations), But this is at the cost of longer indexing times on updates.
Best regards,

Hello everyone
Quick question: Is there any document / URL where I could find out more about how does Basex access the disk during its operation?
For example, are there any reads to be expected during executing a query?
Through iotop, I can see 3-4 processes reading during startup, then another 2, very briefly firing when opening the database and then during querying there are periodic writes (?) but of very brief duration.
I was wondering if there is anything that could be done from the point of view of the hardware to speed up queries (?) (except a more powerful machine at the moment)
All the best Athanasios Anastasiou
