EM::HttpServer vs Thin

 +careo | is there a 25 word version of how it differs from thin?
  +tmm1 | good question.. its probably faster, but only because it doesn't have a real http parser like thin
+wyhaines | It is faster.  It's more of an nginx style parser than the mongrel, grammar based parser.
 +careo | so perhaps a better fit for putting an http interface on top of a bunch of already-evented code?
+wyhaines | careo: It depends.  There are very valid arguments for using an RFC-compliant parser a lot of the time.
+wyhaines | But, yeah, sometimes being strictly RFC compliant isn't something that you care about.
