Hi Pasquale, Note sure what you are seeking the Master database space allocation is the size of the virtuoso.db file on disk ie 138MB and it will grow dynamically as required, thus provided you have more free disk space on the file system as the database grows you should be fine.
More important is the Memory allocation to Virtuoso for hosting the database
working set with the “NumberOfBuffers” INI file param, see the RDF Performance
tuning guide at:
https://virtuoso.openlinksw.com/dataspace/doc/dav/wiki/Main/VirtRDFPerformanceTuning
and monitor the allocated and used buffers with the “status()” command run from
isql
200000 buffers, 183153 used
which is the key to performance ie being able to host the database working in
memory, rather than having to read from disk which kills performance …
Best Regards
Hugh Williams
