I'm just giving Mulgara another try -- this time on a machine with 64-bit
support.
Loading a 100MB file with 1.5M triples worked fine, the import was complete
after 3.5 min.
Now I'm trying to load an 8GB file. The import has been running for almost
a day now, and what worries me is that Mulgara's data directory has only
grown to about 14GB in this time. Moreover the CPU load is rather low, even
though the machine has only one (hyperthreaded) CPU:
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
21944 ejain 16 0 16.1g 1.5g 1.4g S 7 78.8 96:42.30 java
The procedure was initiated through the web-based iTQL shell (using the
LOAD command), maybe there is a better way? I'm also using default settings
pretty much everywhere.
