If this is true, one should be able to compare with benchmarks or evals to demonstrate this.

Anyone know more about this?

Do you have any evidence of this claim? Perhaps a benchmark?

This doesn't align with any of my performance optimization experience.

Can you post a link to any benchmark that would prove that?

larkeith | karma 2658 | avg karma 3.83 · | 2018-09-23 21:30:12

Could you please provide reasoning and evidence for this assertion? Benchmarks, for example?

I'm not so sure that is true. I'd love to see some benchmarking, though.

ekc | karma 160 | avg karma 3.2 · | 2019-02-14 22:35:18+00:00

That's not true in almost any circumstance. What "benchmarks" are you referencing?

phendrenad2 | karma 6687 | avg karma 1.55 · | 2023-07-04 12:44:34

False, the actual performance comes from architectural differences and optimizations.

Significantly?

Have any benchmarks to back that up?

Last time I benchmarked in the language I use most (C++) I couldn't get a difference distinguishable from my margin of error.

Do you have any benchmarks to support that claim?

ivanche | karma 2432 | avg karma 3.48 · | 2020-06-23 14:17:17

Interesting, do you have any benchmarks proving this?

dogol | karma 13 | avg karma 0.37 · | 2023-11-29 16:40:33

any further real experience so to prove it, that's e.g. some Linux tools that can trace/benchmark for this so as to prove it?

jaybill | karma 75 | avg karma 1.97 · | 2012-05-29 20:33:25+00:00

I'm curious what benchmarks you're deriving that from. I've not found that to be the case at all.

wladimir | karma 3587 | avg karma 2.26 · | 2010-12-15 15:59:41+00:00

On which benchmarks? Is this the case for both x86 and x86/64 targets? Do you have any specific reference?

insanitybit | karma 4243 | avg karma 2.69 · | 2023-05-16 10:37:31

Yes, that is what the linked benchmarks discuss...

CorySimmons | karma 32 | avg karma 1.14 · | 2017-03-08 14:42:02

A few comments are mentioning the implementation is probably dated.

Does anyone have benchmarks that tell a different story?

I think that this is a good question that I would also like to know the answer to. Additionally, are there other benchmarks or tests where this issue (possibly) presents itself?

boomlinde | karma 3196 | avg karma 1.8 · | 2013-11-23 21:17:05

Do you have any benchmarks to support your first assertion?

lpgauth | karma 1200 | avg karma 2.51 · | 2017-02-20 01:30:18+00:00

Not really, since it's unclear how this benchmark was conducted. It might just be a tuning issue on the kernel side...

fulafel | karma 12262 | avg karma 1.65 · | 2019-12-06 08:20:53

True. But generally it affects cpu bound benchmarks.

zbjornson | karma 1054 | avg karma 3.93 · | 2016-01-06 01:57:53+00:00

Neat, did not know about that. Will add it to my follow-up benchmarks. Thanks for all the comments. :)
