Copied from comment #10845 (comment) to show the code and run CI

Map/Set always use the default comparison. It should be easy to optimize it... One may think... But I've seen #9348, #513, and related. Such a hopeless state to optimize (inline/devirtualize) the comparison :(

This implementation is probably not 100% compatible with the current behavior. It could be if we apply the logic from #9348 snippet, to exclude records & DUs, if that code is correct.

If we take the current NuGet 5.0 release without any changes to Map as a baseline, are we ready to (Ratio column)

  • [Improve the map performance with] primitive keys by 3.65x - getItem,
  • .. struct T : IComparable<T> by 4.14x - getItemIntLike,
  • .. struct records by 95% - getItemIntRecord
  • .. string by 52% - getItemString,
  • but lose 15% for reference types - getItemRefLike, 17% for reference type records - getItemIntRefRecord

?

I would say that everything could be wrapped by struct T : IComparable<T> + efficient logic there, and if someone uses ref-types as a key they do care about about performance by definition. But I do understand that regressing existing code by 15/17% may be too big. Yet the tradeoff is so great for primitive types.

What do you think? What's the most important use case for the map/set?

The types in the bench are:

    [<StructuralEquality;CustomComparison>]
    type IntLike =
        struct
           val Value: int
           new(v:int) = {Value = v}
           member x.CompareTo(y:IntLike) = x.Value.CompareTo(y.Value)
        end
        
        interface IComparable<IntLike> with
            member x.CompareTo(y) = x.CompareTo(y)
            
        interface IComparable with
            member x.CompareTo(y) = x.CompareTo(y :?> IntLike) 


    type RefLike =
        val Value: int
        new(v:int) = {Value = v}
        member x.CompareTo(y:RefLike) = x.Value.CompareTo(y.Value)
        
        interface IComparable<RefLike> with
            member x.CompareTo(y) = x.CompareTo(y)
            
        interface IComparable with
            member x.CompareTo(y) = x.CompareTo(y :?> RefLike)
            
    [<Struct>]
    type IntRecord =
          { Value1 : int
            Value2 : int
          }

    type IntRefRecord =
          { Value1 : int
            Value2 : int
          }

Map: Optimize away ininst check
9f21d51 
Store height in leaves. Compared to the old discussion, when Left/Right were proposed to be stored in a universal node,
this adds 4 bytes to leaves or 2 bytes per item on average (vs 16/8).
@buybackoff
Map: use if instead of match
aa0572c 
`Match` produces `sub 1` and `switch` instruction. Here, for any non-trivial count,
nodes are more frequent than leaves on the path, so branch prediction should be beneficial.

This is what we could get if using:

  • static read-only field that indicates if a type implements IComparable<T>, like this
  • a custom IL that add .constained modified to callvirt CompareTo when the static field is true (not sure if that is verifiable), like this.
    type CompareHelper<'T when 'T : comparison>() =
        static let c = LanguagePrimitives.FastGenericComparer

        [<MethodImpl(MethodImplOptions.AggressiveInlining)>]
        static member Compare(l:'T, r:'T):int =
            if Spreads.KeyComparer<'T>.IsIComparable then // JIT-time constant
                // add .constained before callvirt to IComparable.CompareTo
                Spreads.Native.UnsafeEx.CompareToConstrained(&Unsafe.AsRef(&l),&Unsafe.AsRef(&r))
            else
                // with IsIComparable as constant all other cases use IComparer directly, as before
                c.Compare(l, r)

Here are the numbers if we only use static readonly and a delegate from reflection.

        [<MethodImpl(MethodImplOptions.AggressiveInlining)>]
        static member Compare(l:'T, r:'T):int =
            if Spreads.KeyComparer<'T>.IsIComparable then
                CompareHelper<'T>.CompareToDlg.Invoke(l,r)
            else
                c.Compare(l, r)

But this time delegates are used for ref-type IComparables

        static member val CompareToDlg : Func<'T,'T,int> =
                let dlg =
                    try
                        if Spreads.KeyComparer<'T>.IsIComparable then // All types, not only structs
                            let dlg = ...
                            dlg
                        else
                            null
                    with _ -> null
                dlg
            with get

Both RefLike and normal record do implement IComparable, and they have significant improvement.

It works quite well now, without static readonly and custom IL.

Related to the changes is fsharp/fslang-suggestions#816. We use IComparable<T> if it is assignable from T, i.e. T implements it.

Strange thing happens with string vs the previous PR, but compared to the base line the improvement is still big.

Previous benchmarks were not correct for some cases in absolute terms (e.g. wrong number of OperationsPerInvoke), but relatively were OK. The updated Map benchmarks are here: https://github.com/buybackoff/fsharp-benchmarks

It's unambiguous. If it does something different than other ways to compare then it's very weird.

Hmmmm. The regression for reflikes in your testing is troublesome. I can't speak towards overall usage, but within the compiler we definitely make heavy use of reference types and this would negatively affect that.

Yes, when I was writing "<5% mostly edge cases" of course I was biased towards my own usage patterns...

Overall, these things look too complicated. I opened the draft PRs mostly for CI and to show the magnitude of possible improvements. I'm glad that I was able to split the whole Map/Set story into independent steps. If you close these 2 comparer PRs I'm fine with it. A was aware of the comparer inefficiency for a long time. But I'm rather out of the loop these days and when I've learned all the complexity and history of the comparison vs Comparer<T>.Default issue I realized it's too much to push forward with this. It's a much bigger issue than just Map/Set.
