[Seaside] speed of VM vs. speed of database

if objects and tables with relations where truly comparable, objet-relational-impedance-mismatch  would not exist.
In the other hand if you use a BTree of objects indexed in the way you need, your speed will have no match in the RDBMS world.
Proper use of Gemstone, omnibase or even a modest index persisted in the image (a facade to a BTree or something like that) will satisfy quite high expectations.
Have in mind that, for performance, the only metric that really counts is the user experience.
Maximize anything else and you'll be heading to a non human centered artifact, faster.
BTW, this could be off topic but in the economy there is an anti-pattern familiar to this when you see companies maximizing profit instead of wealth creation.
