* benchmark/bm_io_nonblock_noex2.rb: new benchmark based on bm_io_nonblock_noex.rb * io.c (io_read_nonblock): move documentation to prelude.rb (io_write_nonblock): ditto (Init_io): private, internal methods for prelude.rb use only * prelude.rb (IO#read_nonblock): wrapper + documentation (IO#write_nonblock): ditto [ruby-core:71439] [Feature #11339] rb_scan_args and hash lookups for kwargs in the C API are clumsy and slow. Instead of improving the C API for performance, use Ruby instead :) Implement IO#read_nonblock and IO#write_nonblock in prelude.rb to avoid argument parsing via rb_scan_args and hash lookups. This speeds up IO#write_nonblock and IO#read_nonblock benchmarks in both cases, including the original non-idiomatic case where the `exception: false' hash is pre-allocated to avoid GC pressure. Now, writing the kwargs in natural, idiomatic Ruby is fastest. I've added the noex2 benchmark to show this. 2015-11-12 01:41:12 +0000 target 0: a (ruby 2.3.0dev (2015-11-11 trunk 52540) [x86_64-linux]) target 1: b (ruby 2.3.0dev (2015-11-11 avoid-kwarg-capi 52540) ----------------------------------------------------------- benchmark results: minimum results in each 10 measurements.
