Testing server response time is not something you should put much time in hand-rolling yourself. There are a number of utilities that do this, not all in perl. I've had decent success with Apache JMeter, but that doesn't mean you shouldn't research other tools.

I'm not here to plug jmeter, but it's worked great for me in monitoring response time under load.

I'd be very curious if other monks have successfully handled this type of issue purely with perl, since I've always wanted to but never *needed* to (due to the presence of existing utilities.)

    [Corion]: And a good daypart to you as well, Lady_Aleena !
    [robby_dobby]: Hey monkeys, do you ever get the realization that you're all waking up to chaos? I suppose not :P
    [Lady_Aleena]: Good morning Corion, I hope you have a wonderful day as well. 8)
    [Corion]: Yesterday I encountered an interesting data structure problem. I have a remote program that emits events, and my client listens for these events with one-shot callbacks, that is, I register the callback and if the event gets generated that callback ...
    [Lady_Aleena]: robby_dobby, every day. Chaos is my life with few controls.
    [Corion]: ... gets called once. The data structure for that is just a hash of arrays, mapping the event type to a queue of registered one-shots, and the first one-shot from the queue gets removed and called.
    [Corion]: But now I want to register a one-shot for two events, of which only one will arrive, so my data structure doesn't work anymore...
    [Lady_Aleena]: Corion, ouchy.
    [Corion]: (maybe I should write this up as a SoPW) - currently, the "most efficient" data structure I come up with is a single array which I scan for the first fitting one-shot. Not efficient but I don't expect more than five outstanding one-shots anyway
    [choroba]: can't you create a meta-key corresponding to the disjunction of the events?
