Rich, you will need to adjust your heap space to
take advantage of your RAM. See the FAQ at
http://www.topquadrant.com/products/TBS_FAQ.html#TBC7
For general guidelines on the size of heap needed, pleas
see that FAQ at

Hi. I am using TBC SE 4.2.0 and I'm trying to load a
large model (~ 4M triples) into TBC using the native in-memory
store. I am not currently using an external triple store, though I
see one in my future. Is it unreasonable to expect TBC to handle a
large model of this size? Are there performance settings I should
be tweaking? I get the following error, which I imagine is
traceable to memory consumption, but can't be sure. I have 8G
memory on my Mac.
