[ruby-core:45900] [ruby-trunk - Feature #6615] Release GVL in zlib when calling inflate() or deflate()
From:
"drbrain (Eric Hodel)" <[email protected]>
Date:
2012-06-26 21:57:17 UTC
List:
ruby-core #45900
Issue #6615 has been updated by drbrain (Eric Hodel).
Since the last benchmark is so close, this benchmark uses the same deflate file set, but adds GVL contention by deflating the set across four threads. Since no buffer expansion occurs this will benchmark cost of GVL release vs rb_thread_schedule() in present Zlib code.
Code:
require 'zlib'
require 'benchmark'
r = Random.new 0
file_count = 100_000
deflated = (0..file_count).map do
input = r.bytes 1000
Zlib::Deflate.deflate input
end
times = Benchmark.measure do
(0..3).map do
Thread.new do
deflated.each do |input|
Zlib::Inflate.inflate input
end
end
end.each do |t|
t.join
end
end
puts times
Without patch:
$ for f in `jot 5`; do ruby20 test.rb; done
5.420000 5.970000 11.390000 ( 8.162893)
5.400000 6.270000 11.670000 ( 8.263046)
5.460000 5.920000 11.380000 ( 8.133742)
5.410000 6.290000 11.700000 ( 8.289913)
5.500000 6.620000 12.120000 ( 8.478085)
With patch:
$ for f in `jot 5`; do make runruby; done
5.120000 6.240000 11.360000 ( 8.039715)
5.240000 6.260000 11.500000 ( 8.097961)
5.280000 5.940000 11.220000 ( 8.004246)
5.210000 6.360000 11.570000 ( 8.171124)
5.240000 6.200000 11.440000 ( 8.054929)
Again, slight improvement, but not as great as the video.
The inflate function is able to operate in parallel a small fraction of the time which is able to make up for the cost of GVL release/acquire.

Feature #6615: Release GVL in zlib when calling inflate() or deflate()
https://bugs.ruby-lang.org/issues/6615#change-27500
Author: drbrain (Eric Hodel)
Status: Open
Priority: Normal
Assignee:
Category: ext
Target version: 2.0.0
This patch switches from zstream_run from using rb_thread_schedule() to rb_thread_blocking_region().
I don't see a way to safely interrupt deflate() or inflate() so the unblocking function is empty.
This patch should allow use of output buffer sizes larger than 16KB. I suspect 16KB was chosen to allow reasonable context-switching time for ruby 1.8 and earlier. A larger buffer size would reduce GVL contention when processing large streams.
An alternate way to reduce GVL contention would be to move zstream_run's loop outside the GVL, but some manual allocation would be required as currently the loop uses a ruby String as the output buffer.
