An optimization thought

Today's random optimization thought, brought to my mind by the processof trying to make DWiki run slightly faster:

Caches are the degenerate brute force case of this, but programrestructuring is better. Repeatedly calling the same core routine canbe a sign that the upstream interfaces aren't really doing what higherlevels want, so the higher levels have to do redundant work.

Besides, if you can figure out a way to call

Some little things Firefox gets right

One of the marks of good software is that it understands how usersthink it works, and makes itself work that way. Two little bits ofhow Firefox works make a good illustration of this.
