2017-10-24Lazy Proc allocation for block parametersko1
[Feature #14045] * insns.def (getblockparam, setblockparam): add special access instructions for block parameters. getblockparam checks VM_FRAME_FLAG_MODIFIED_BLOCK_PARAM and if it is not set this instruction creates a Proc object from a given blcok and set VM_FRAME_FLAG_MODIFIED_BLOCK_PARAM. setblockparam is similar to setlocal, but set VM_FRAME_FLAG_MODIFIED_BLOCK_PARAM. * compile.c: use get/setblockparm instead get/setlocal instructions. Note that they are used for method local block parameters (def m(&b)), not for block local method parameters (iter{|&b|). * proc.c (get_local_variable_ptr): creates Proc object for Binding#local_variable_get/set. * safe.c (safe_setter): we need to create Proc objects for postponed block parameters when $SAFE is changed. * vm_args.c (args_setup_block_parameter): used only for block local blcok parameters. * vm_args.c (vm_caller_setup_arg_block): if called with VM_CALL_ARGS_BLOCKARG_BLOCKPARAM flag then passed block values should be a block handler. * test/ruby/test_optimization.rb: add tests. * benchmark/bm_vm1_blockparam*: added. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@60397 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2017-10-24file.c: apply2files releases GVLnormal
This means File.chmod, File.lchmod, File.chown, File.lchown, File.unlink, and File.utime operations on slow filesystems no longer hold up other threads. The platform-specific utime_failed changes is compile-tested using a new UTIME_EINVAL macro This hurts performance on fast filesystem, but these methods are unlikely to be performance bottlenecks and (IMHO) avoiding pathological slowdowns and stalls are more important. benchmark results: minimum results in each 3 measurements.

2017-10-04Dir.empty? releases GVLnormal
This converts all slow syscalls in the Dir.empty? implementation to release GVL. We avoid unnecessarily GVL release and reacquire for each slow call (opendir, readdir, closedir) and instead only release and acquire the GVL once in the common case. Benchmark results show a small degradation in single-threaded performance: Execution time (sec) name trunk built dir_empty_p 0.689 0.758 Speedup ratio: compare with the result of `trunk' (greater is better) name built dir_empty_p 0.909 * dir.c (rb_gc_for_fd_with_gvl): new function (nogvl_dir_empty_p): ditto (dir_s_empty_p): use new functions to release GVL * benchmark/bm_dir_empty_p.rb: new benchmark [ruby-core:83071] [Feature #13958] git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@60111 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2017-10-01File#rename releases GVLnormal
rename(2) requires two pathname resolution operations which can take considerable time on slow filesystems, release the GVL so operations on other threads may proceed. On fast, local filesystems, this change results in some slowdown as shown by the new benchmark. I consider the performance trade off acceptable as cases are avoided. benchmark results: minimum results in each 3 measurements.

2017-09-29array.c: improve operations on small arraysnobu
[Feature #13884] Reduce number of memory allocations for "and", "or" and "diff" operations on small arrays Very often, arrays are used to filter parameters and to select interesting items from 2 collections and very often these collections are small enough, for example: ```ruby SAFE_COLUMNS = [:id, :title, :created_at] def columns @all_columns & SAFE_COLUMNS end ``` In this patch, I got rid of unnecessary memory allocations for small arrays when "and", "or" and "diff" operations are performed. name | HEAD | PATCH -----------------+------:+------: array_small_and | 0.615 | 0.263 array_small_diff | 0.676 | 0.282 array_small_or | 0.953 | 0.463 name | PATCH -----------------+------: array_small_and | 2.343 array_small_diff | 2.392 array_small_or | 2.056 name | HEAD | PATCH -----------------+------:+------: array_small_and | 1.429 | 1.005 array_small_diff | 1.493 | 0.878 array_small_or | 1.672 | 1.152 name | PATCH -----------------+------: array_small_and | 1.422 array_small_diff | 1.700 array_small_or | 1.452 Author: Dmitry Bochkarev <dimabochkarev@gmail.com> git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@60057 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2017-05-27benchmark: Rename to bm_erb_render.rbk0kubun
from bm_app_erb_render.rb. I'm told from ko1 that bm_app_* is namespace for Ruby applications, not for ERB and we should use bm_erb_* for ERB benchmark instead. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@58915 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2017-05-26erb.rb: Generate static string with opt_str_uminusk0kubun
to skip object allocation for static string. We can't always enable frozen_string_literal pragma because we can't freeze string literals embedded by user for backward compatibility. So we need to use fstring for each static string. Since adding ".freeze" to string literals in #content_dump is slow on compiling, I used unary "-" operator instead. benchmark/bm_app_erb_render.rb: Added rendering-only benchmark to test rendering performance on production environment. This benchmark is created to reproduce the behavior on Sinatra (Tilt). Thus it doesn't use ERB#result to skip parsing compiled code. It doesn't use ERB#def_method too to regard `title` and `content` as local variables. If we use #def_method, `title` and `content` needs to be method call. I wanted to avoid it. This patch's benchmark results is: * Before app_erb_render 1.250 app_erb 0.704 * After app_erb_render 1.066 app_erb 0.686 This patch optimizes rendering performance (app_erb_render) without spoiling (total of rendering +) compiling performance (app_erb). git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@58905 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2017-05-04benchmark/bm_vm_thread_pass_flood.rb: add commentnormal
I was about to write off this benchmark while working on GVL improvements on multi-core systems. However I noticed it exposes a weakness in my work-in-progress code when I tested on an old single CPU system. Further testing reveals setting CPU affinity ("schedtool -a 0x1" on Linux) on a modern multi-core system is enough to reproduce the problem exposed by this benchmark. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@58571 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

"lazy_sweep" does not appear to have ever been a valid kwarg for GC.start, however the opposite of "lazy_sweep" appears to be "immediate_sweep". So use immediate_sweep, and flip the boolean value of each arg. I guess this only started failing with r56981 in Dec 2016 ("class.c: missing unknown_keyword_error", commit e3f0cca2f26ba44c810ac980cdff7dda129ae533) * benchmark/bm_vm1_gc_wb_ary.rb: "lazy_sweep: false" => "immediate_sweep: true" * benchmark/bm_vm1_gc_wb_ary_promoted.rb: ditto * benchmark/bm_vm1_gc_wb_obj.rb: ditto * benchmark/bm_vm1_gc_wb_obj_promoted.rb: ditto git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@58565 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2015-12-11hash.c (rb_num_hash_start): avoid pathological behaviornormal
The OR-ing itself is bad for a hash function, and shifting 3 bits left was not enough to undo the damage done by shifting (RUBY_SPECIAL_SHIFT+3) bits right. Experimentally, shifting 16-17 bits seemed to work well in preparing the number for murmur hash. Add a few more benchmarks to based on bm_hash_shift to ensure we don't hurt performance too much with tweaks. I'm pretty confident about this change and commiting it now; especially since we're still using Murmur behind it (but perhaps we can update to a newer hash from Murmur...)

2015-11-12io.c: avoid kwarg parsing in C APInormal
* 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.
