Hi Sumit,
Firstly, why are you using a build from 07.00.3203 build from August 2013, as
the latest open source builds are 07.10.3208 from Feb 2014 as detailed at:
http://virtuoso.openlinksw.com/dataspace/doc/dav/wiki/Main/VOSNews#2014-02-17%20--%20Virtuoso%20Open-Source%20Edition%207.1.0%20Released
Please also refer to the following tip on deleting large graphs:
http://virtuoso.openlinksw.com/dataspace/doc/dav/wiki/Main/VirtTipsAndTricksGuideDeleteLargeGraphs
Also, how much memory do you have available and has your Virtuoso instance been
tuned to make use of this available memory for best performance as detailed at:
http://virtuoso.openlinksw.com/dataspace/doc/dav/wiki/Main/VirtRDFPerformanceTuning
Please check with the "status(''); command to ensure the "buffers" indicated as
available matches the "NumberOfBuffers" set in the INI file, in fact please
provide the output of running the command ...
Best Regards
Hugh Williams
