The main problem is this.... the portage database is a file system based
mechanism. That is to say, when you update, search or otherwise use emerge,
the program is busy as hell leafing through thousands of files looking for
what you want..

"Hashed", "indexed"??? Not even close....

Portage is begging for a decent database engine and I pray it's sql
based....

The other hitch is that portage is written in an interpreted language,
Python. Python is an excellent programming language, no doubt about it, but
performance isn't one of it's highlights. Moving portage to C would be so
much better....
