In 2006 it was literally minutes on an NSLU2 ["low-memory mode."] Some shell strings were manipulated with code that used fork+exec numerous times instead of standard tricks of no-fork processing with strings in an interpreter. The supposed shell builtin "[" actually was *not* builtin. [Track PID with "ps" in another window.] Some sets of packages were tracked using a string of concatenated names instead of with zero-length files in a temporary directory. One step was at least O(n**2) in the number of packages. I complained; the response seemed to me, "Be glad it works at all." -- -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe". Trouble?
