Which is generally a cache local activity, probably not even as expensive as a system call (although I admit I haven't benched it with that in mind and it could vary by platform). I do know that back when I _did_ bench it for overall performance, it did quite well. The alternative is keeping the config file and all its compiled regexes in memory with a more complicated data structure. (Admittedly platforms that want a large config file are unlikely to be memory constrained, but still.) > Volunteers to fix that? I have a tropism for _simple_. This entire discussion seems to me to be about how to complicate mdev for questionable gains. I guess I still have toybox. :) Rob -- "One of my most productive days was throwing away 1000 lines of code." - Ken Thompson. _______________________________________________ busybox mailing list [email protected] http://busybox.net/cgi-bin/mailman/listinfo/busybox
