So what's the concenus here? I don't really care for threads, never have. The daemon seems to run fine on my dual core machine and my quad core machine; I see activity on all of the cores via a system monitor. SMP has come a long way as well, and may be just as clever without threads (mere speculation here). I already had the realization that this project wasn't going to scale fantastically as soon as I chose Ruby for the language. It's not something that I expect to be deployed widely, but more of a "hey cool I want to run a jabber server" kind of thing. I wrote it for me mostly, with a userbase of less than a few hundred. It'd be cool to see it running somewhere, but mostly it's for me, to "scratch the itch" as it were. All of my programs were written "for me" but I always release my code because someone might find it useful. That doesn't mean I don't take measures to help performance. Each connected user only incurs about 5-10 objects. An XMPP::Stream, an XMPP::Resource, and a handful of REXML element objects (stored stanzas for things like presence). The performance will also increase dramatically with Ruby 1.9 as 1.9 moved from interpreted to bytecode, so the performance gain is a few orders of magnitude. I'm fairly sure it'll be out before my code is done (Christmas ish). I tend to agree that if I can stay away from threads I should. I like to be able to follow my code flow.
