In answer to some cwm scaling/performance questions, I wrote:

<DanC> $ time python ~/w3ccvs/WWW/2000/10/swap/cwm.py --rdf cyc.daml
--filter=subc.n3 -n3 >,cyc-sub.n3
<DanC>  
<DanC> real    0m43.022s
<DanC> user    0m38.761s
<DanC> sys     0m0.385s
<DanC> the query just finds all subClassOf triples: { ?C1 s:subClassOf
?C2 } => { ?C1 s:subClassOf ?C2 }.


where cyc.daml is http://opencyc.sourceforge.net/daml/cyc.daml
$ wc cyc.daml
  40863  203574 2436919 cyc.daml

$ wc ,cyc-sub.n3
  3999   7243 133947 ,cyc-sub.n3
