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.... -- ****************************************************************************** Registered Linux User Number 185956 FSF Associate Member number 2340 since 05/20/2004 Join me in chat at #linux-users on Buy an Xbox for $149.00, run linux on it and Microsoft loses $150.00! 10:50pm up 53 days, 1:32, 6 users, load average: 3.07, 2.99, 2.93 -- gentoo-performance@g.o mailing list
