{ $subheading "Performance" }

{ "Continuations are now supported by the static stack effect system. This means that the " { $link infer } " word and the optimizing compiler now both support code which uses continuations." }
{ "Many words which previously ran in the interpreter, such as error handling and I/O, are now compiled to optimized machine code." }
{ "A non-optimizing, just-in-time compiler replaces the interpreter with no loss in functionality or introspective ability." }
{ "The non-optimizing compiler compiles quotations the first time they are called, generating a series of stack pushes and subroutine calls." }
{ "The optimizing compiler now performs some more representation inference. Alien pointers are unboxed where possible. This improves performance of the " { $vocab-link "ogg.player" } " Ogg Theora video player considerably." }
{ "The queue of sleeping tasks is now a sorted priority queue. This improves performance considerably when there is a large number of sleeping threads (Doug Coleman)" }
{ "Improved hash code algorithm for sequences" }
{ "New, efficient implementations of " { $link bit? } " and " { $link log2 } " runs in constant time for large bignums" }
{ "New " { $link big-random } " word for generating large random numbers quickly" }
{ "Improved profiler no longer has to be explicitly enabled and disabled with a recompile step; instead, the " { $link profile } " word can be used at any time, and it dynamically patches all words in the code heap to increment call counts. There is no overhead when the profiler is not in use." }
