The comparison of Brahms to three systems implemented, in part, for general query answering (with the expressive power of SPARQL) seems a bit unfair. Brahms is implemented in a way so as to speed association queries while ignoring features of more general query languages. In contrast, the three systems it is compared to use techniques that speed SPARQL query execution, but dramatically slow down association queries. While this point of difference is legitimately made, a fairer comparison might have been made by, for example, removing the default compound indexes in Redland (which are never used in the association discover algorithms) at the same time as adding the new association-specific index. Such removal would have a direct affect on the memory usage tests presented in section 6.2 in which the "Redland, IDX" variant ran out of memory.
