OWLIM is not free software so is not useable for OKF's purposes. This
is "free" in the sense of freedom not cost. For other projects it may
be a viable choice.

TDB is outperformed by Virtuoso and 4store which is why these are the
ones being configured.

Part of the reason for my 96 byte strawman to the semantic-web@ list
was to try to get an idea of the real properties of these things, BSBM
is useful for measuring raw performance but says little about
operational difficulties or or resource requirements (and I note their
benchmark machine is sized roughly according to my strawman).

If you are aware of any published rigorous comparisons of the
alternatives that cover actual real-world engineering requirements
from RDTF or elsewhere I would love to hear about them.

Cheers,
