I haven't done a performance comparison of the two systems.  I suspect  
that Acache is probably faster at least for certain tasks.  Disk and  
memory layout as well as the transaction architecture have large  
impacts on what works well and doesn't and they've optimized for  
certain operations (such as ops over RDF triples).  Also it's tightly  
integrated into the Allegro lisp/compiler/IO layer, doesn't have  
multiple backends so suffers from less indirection, etc.

It would be interesting to get some data if you have it; I'd like to  
do a lisp-only version of Elephant someday and ACache is close enough  
that it might make sense to borrow from the architecture to get some  
of the same performance that they've managed to produce.

Cheers,
Ian
