15 "Portage deficency"? You mean the fact that python scans some thousands of
16 files in the file based database, writing as it goes?

20 Yup, from thousands of files in the file based database...

22 Portage is a wonderful tool for package management, but the sheer size of the
23 beast begs for movig it to C and a proper database. I remember in the early
24 days of my gentoo experience that portage wasn't a bother. But as ebuilds are
25 added to portage and my choice of installed ebuilds grows... portage has
26 become quite a slug performance wise. I guess this is where the IT types step
27 in and say it scales poorly.

29 Cheers all and Happy New Year to everyone.
