Potential regression: Dictionary of Value Types #13137

Closed adamsitnik closed 2 years ago

adamsitnik commented 5 years ago

It looks like TryGetValueFalse, IndexerSet and ContainsKeyFalse benchmarks have regressed for Dictionaries of Value Types (at least for int).

If you run the benchmarks from command prompt on Windows remember to escape the < and > characters https://stackoverflow.com/questions/251557/escape-angle-brackets-in-a-windows-command-prompt

@adamsitnik thanks for the finding, will you be following up on this issue, to assign it to you?

BruceForstall commented 5 years ago

@safern @adamsitnik Does this need to be a 3.0 issue?

danmoseley commented 5 years ago

@adamsitnik System.Collections.IndexerSet.Dictionary(Size: 512) appears twice, because of two GenericTypeArguments. From your comments it sounds like the first one is the typeof(int) one but I wonder whether BDN could somehow disambiguate it's output? Even if it was the index of the parameter (1, 2)

danmoseley commented 5 years ago

My take (I am interested in @billwert @safern @adamsitnik thoughts) is that we probably do not want to attempt to address this in 3.0 because the code here (whether in Dictionary or codegen) is subtle and easy to regress perf elsewhere. We have some great wins in many other common scenarios here and we can see whether we get feedback on this scenario.

billwert commented 5 years ago

Doesn't sound like it meets any bar for 3.0 to me. Agree we should act based on feedback.
