[ruby-core:50523] [ruby-trunk - Bug #6183] Enumerator::Lazy performance issue
From:
"gregolsen (Innokenty Mikhailov)" <anotheroneman@...>
Date:
2012-12-03 13:28:04 UTC
List:
ruby-core #50523
Issue #6183 has been updated by gregolsen (Innokenty Mikhailov).
File December_3.diff added
I've merged the patch with latest trunk (see latest diff attached), specifically with Enumerator lazy size feature.
Also I've removed the ugly case switch: proc entry stores pointer to a function that is executed when iterating over the elements.
So now it even resembles the current implementation a bit.
Please, let me know your thoughts about all this.
Thanks in advance.
----------------------------------------
Bug #6183: Enumerator::Lazy performance issue
https://bugs.ruby-lang.org/issues/6183#change-34361
Author: gregolsen (Innokenty Mikhailov)
Status: Assigned
Priority: Low
Assignee: mame (Yusuke Endoh)
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.
