[Zope3-dev] [INFO] updated relation store in cpsskins

[Jean-Marc Orliaguet]

Hi!

I've updated the relation store's index in cpsskins to support wildcards
on triadic relations.

http://www.z3lab.org/sections/blogs/jean-marc-orliaguet/2005_08_27_triadic-relations

It gives extremely good scalability from 1 to 100000+ users (the script
used to measure query times is attached in the mail and in the 0.035 ms
a third of the time stands for function call overhead)

It seems that looking up an index key in a python dictionary is faster
than lookup up an the same key from an OOBTree, I haven't tried with
IOBTrees though.

regards
/JM
