Hello, it's since 2007 that cache for dpkg has been proposed but maintainers never replied. For this reason I've written a shared library libtdpkg.so to wrap open/fstat/rename/unlink calls from dpkg for .list files in order to cache the contents of those files. The result is quite impressive on how it boosts up cold startup of dpkg (from 14s to 2-3s here using tokyocabinet). Here's the homepage for reference: http://lethalman.hostei.com/tdpkg.html It's robust enough to not fuck up /var/lib/dpkg/info, the first time it should be run as root in order to create the cache in /var/lib/dpkg/info/tdpkg.cache. I'd like to hear your comments about any possibility to enhance the cache concept inside dpkg. Best regards, -- http://www.debian.org - The Universal Operating System
