Exact same test here (on a different machine than I posted earlier with but that doesn't really matter). [breser@titanium utils]$ time ./rpmmon.pl -p xmms -t maints gc 1.23user 0.64system 0:04.03elapsed 46%CPU (0avgtext+0avgdata 0maxresident)k 0inputs+0outputs (1240major+675minor)pagefaults 0swaps Same test with the code in my CGI script. On the same machine as above. 0.27user 0.00system 0:00.42elapsed 63%CPU (0avgtext+0avgdata 0maxresident)k 0inputs+0outputs (436major+322minor)pagefaults 0swaps That's 9 times faster. Now maybe on a tool when you're running it by hand on a command line you don't care that you have to wait. But when you shove it on a webserver and make it accessible to the world speed is the difference between and overwhelmed server and one that runs nicely. At any rate I thought I saw why there is the difference. You allow people to query multiple packages by separating them with a comma. To support this you load the entire list of packages and maintainers into a hash. This takes a little bit of time and isn't very efficent when you only want one entry. What I did is only allow for one package. I open the file and search for the result when I find it I quit. So I tried to graft a modified version of this into rpmmon.pl. No speedup in time. So I'm really not sure what's slowing it down. But it has to do with the code that is run from package_maintainer because if I comment all the calls there it ruturns quickly. In other words I've eliminated the other overhead of the program (including perl compilation) as the problem. > It's nice that you provide a cgi way to have maintainers but I > don't see what I can do with your code. Ohh I wasn't really suggesting that you do anything with it. I was providing it so if you wanted to see how I'd done it and was getting different results as far as execution speed. Anyway I've got other things to work on at the moment as I'm sure you do so I'll table this for now. Maybe when I get a chance I'll come back and look at this. -- Ben Reser <[EMAIL PROTECTED]> http://ben.reser.org What difference does it make to the dead, the orphans, and the homeless, whether the mad destruction is wrought under the name of totalitarianism or the holy name of liberty and democracy? - Ghandi
