Hi George,
I’m not sure if your queries are using the full-text at all, as a minimum of 8 seconds doesn’t sound that thrilling. Could you please check the output in the InfoView panel in the GUI (or the command-line output created via -V) and see what’s written there? Next, feel free to pass us on one of the queries you have tried.
Best, Christian ___________________________

Hi community,
I have created a DB of around 7 GB documents in BaseX (100 first records of Medline) with full text index option enabled (index size 1 GB).
I test it locally on my laptop. The problem is that I observe great variations in the free text query times from 8s up to couple of minutes. Main memory is underused (allocated 2 GB) and the processor has quite low utilization. I observe high usage of the hard disk. I have read that the whole db could be loaded in the main memory, but this is not an option for an 100 GB db collection that I would like to have.
My question is if there is a possibility to load only the index in the main memory in order to accelerate the process of searching. Any other performance tips are very welcome.
Thank you, George Aravanis _______________________________________________ BaseX-Talk mailing list BaseX-Talk@mailman.uni-konstanz.de https://mailman.uni-konstanz.de/mailman/listinfo/basex-talk
