[ruby-core:45076] [ruby-trunk - Bug #6183] Enumerator::Lazy performance issue
From:
"gregolsen (Innokenty Mikhailov)" <anotheroneman@...>
Date:
2012-05-16 08:15:31 UTC
List:
ruby-core #45076
Issue #6183 has been updated by gregolsen (Innokenty Mikhailov).
File 16_may.diff added
File new_bench.rb added
=begin
Here's an update.
All methods except (({Lazy#cycle})), (({Lazy#zip})) and (({Lazy#flat_map})) are optimized.
Benchmark results shown below.
I was working in ((<this branch|URL:https://github.com/gregolsen/ruby/tree/lazy_enumerator_optimization>)).
Cycle, zip and flat_map are really tough to convert to procs chaining, however they are working fine in this hybrid solution and can be leave as it is.
All tests pass except test_inspect.
If this implementation is acceptable then the next step will be to fix inspect and add more tests to cover different types of chaining:
like chaining of enumerator chained (cycle, zip, flat_map) methods with procs chained optimized methods.
Please, let me know your thoughts.
Thanks.

Bug #6183: Enumerator::Lazy performance issue
https://bugs.ruby-lang.org/issues/6183#change-26654
Author: gregolsen (Innokenty Mikhailov)
Status: Assigned
Priority: Low
Assignee: nobu (Nobuyoshi Nakada)
Category:
Target version:
ruby -v: ruby 2.0.0dev (2012-03-17 trunk 35075) [x86_64-linux]
I benchmarked Enumerator::Lazy and that's what I got:
user system total real
Lazy: 0.690000 0.010000 0.700000 ( 0.733160)
Normal: 0.160000 0.010000 0.170000 ( 0.186695)
It seems like even with 4 chain links and 3000 elements in initial array, Lazy enumerator is almost 4(!) times slower than the normal case.
Instead of performance benefit we've got 4 times performance drawback.
See test file attached.
