That statement isn't correct. Please don't make it since I don't think the author of Thin or the authors of Mongrel would say that. Oh, well they'd say my stuff is a masterwork, just not that Thin is an incarnation of Mongrel. :-) > Overall the results were not so surprising but at least there's a > little more hard data for people to look at while making decisions > about this stuff. > > Summary 1: Fair proxy can boost performance significantly on sites that > have a mix of 95% fast (<1s) and 5% slow-ish (4s) pages. > > Summary 2: Unix sockets are probably 4% faster than IP sockets (and > therefore Thin is about 4% faster than Mongrel). I don't think it's unix sockets vs. ip sockets. These days those aren't really that much faster than a localhost connection thanks to advancements in performance for internal IPC. Still, 4% increase for all that work done in Thin is kind of lame. These kinds of results keep bringing me back to the real problem: Ruby. It's not what IO loop you use, or threading model, or socket type, but more just that Ruby is slow and it's processing sucks. Another comment I'd make is, why not also release the methodology you gave. I'm actually working on a presentation for RuPy so if you'd like to hack on a repeatable study with an automated report let me know. Could be a good test for what I'm writing for the conference. -- Zed A.
