As it reads, it is allocating memory for, and creating a very large in memory structure. I think it also verifies the files associated with the package, and does some other sanity checks. IMO, about the only way to get real speedup is for all of this data to be in a hashed database, on disk, so all dpkg has to do is open the database and verify files. The hash will already be avaiable. However, there are probably some caveats to this. -- -----------=======-=-======-=========-----------=====------------=-=------ / Ben Collins -- ...on that fantastic voyage... -- Debian GNU/Linux \ ` [EMAIL PROTECTED] -- [EMAIL PROTECTED] -- [EMAIL PROTECTED] ' `---=========------=======-------------=-=-----=-===-======-------=--=---'
