I was actually interested in checking out the sources and experimenting with Jena in general. I already noticed you guys use linux or OS/X. For our particular use case we probably will not exceed a million triples on short term.

I guess I-or-someone needs to find a windows machine - I have one now that I can control and setup for debug. (As you may have guessed, many of use are Linux, some OS/X, for development.) You have an 8G machine - 64 bit java would be good anyway. A 64 bit JVM is essential for TDB at even middling scale as Java can only address about 1.5G and that's not a big disk cache for a decent size database. On 64 bit, it swaps to memory mapped files; on 32 bit TDB does it's own caching (else your DB would be limited to about 1.5Gbytes). Do you need tdbloader3? tdbloader should work reliable on Windows (tdbloader2 is linux only - but it's faster only when you get to 100's million of triples in my experience). Andy
