Hi Dan,
The main places Virtuoso setup and tuning information can be found are:
http://docs.openlinksw.com/virtuoso/databaseadmsrv.html#ptune
http://docs.openlinksw.com/virtuoso/rdfperformancetuning.html
I saw the git issue and commit you made regarding the NFS issue you encountered
which we shall be reviewing.
The only issue I have come across with NFS was with regards to file locking
required by the virtuoso.lck, thus an INI file param is provided to specify an
alternative location for it as detailed at:
http://docs.openlinksw.com/virtuoso/databaseadmsrv.html#ini_Database
Best Regards
Hugh Williams
