Could the regressions in Perf_Single, Perf_Double, Perf_NumberCultureInfo be related to #102683 @huoyaoyuan ? It looks like there was a discussion on the PR about possible perf implications for Mono. Is the regression expected @fanyang-mono ?

The original PR has benchmark on mono and didn't see such regressions on other formats and values: #102683 (comment)

I'll run with the exact values from performance repo again.

Thank you, you can try using https://github.com/dotnet/performance/blob/main/scripts/benchmarks_local.py script to run the selected microbenchmarks on different commits (note, it currently doesn't support a diff between AOT runs so it has to be calculate) There is a Readme with instructions on how to use it. cc: @LoopedBard3

I had some trouble building with benchmark_local.py, just manually comparing the commits a4407a106f883a6593105a660d44da6f8fa4017c and 555dde482e5e76bc0563757b53baee9f0d859a4b.

The difference is generally less than 5%, so it doesn't seem to be caused by #102683

I had some trouble building with benchmark_local.py, just manually comparing the commits a4407a106f883a6593105a660d44da6f8fa4017c and 555dde482e5e76bc0563757b53baee9f0d859a4b.

Results for a4407a106f883a6593105a660d44da6f8fa4017c (After merge):

Results for 555dde482e5e76bc0563757b53baee9f0d859a4b (Before merge):

The difference is generally less than 5%, so it doesn't seem to be caused by dotnet/runtime#102683

Could you please share what issues did you encounter?

I would use something like: python3 benchmarks_local.py --commits a4407a106f883a6593105a660d44da6f8fa4017c 555dde482e5e76bc0563757b53baee9f0d859a4b --run-types MonoAOTLLVM --filter "*Perf_Double.ToString*" to run the Perf_Double.ToString* microbenchmarks.

I'm using the similar command line with --allow-non-admin-execution. It fails for the pack step with following errors:

Can you confirm that the regression is unrelated to #102683?

Thank you for the error log. It looks similar to #103486. Do you think it could be related @LoopedBard3 ?

I've done a quick run with sudo and got:

Looks like there is a measurable regression between the 2 commits.

Yup, I think the error looks related to #103486, or at the very least another set of files that need to be added to the list.

@huoyaoyuan In my last comment I shared the results reproducing the regression. Do you need any more assistance with measurements or something else?

I were just busy these days. Will try to run it tomorrow.

I'm finally able to execute the benchmark script under WSL. On Windows it continuously fails with different attempts.

Analysis: there are many leaf calls of TNumber.IsXXX etc. If mono fails to inline and devirtualize all of them, it can be a source of regression, especially for regular (small) precision.

Thank you for investigating. It's definitely possible but I cannot tell with certainty if they get inlined/devirtualized from top of my head.

Another idea I got when looking at your PR was the change from using TryRunDouble/TryRunHalf to generic TryRun<TNumber>. In many scenarios, the Mono LLVM codegen fallbacks to Mono mini codegen (much less optimized) when encountered with generics so eventually causing worse code to be generated. (fyi: @steveisok)

It's closed to feature complete for .NET 9. Should we go with the regression, or revert the overloads for float and double? The generic version can be used for less-important types, including Half and BFloat16.

@huoyaoyuan Before answering your question, I would like to understand the purpose of your PR. Was the goal to simplify the library code or to enhance CoreCLR performance? If it was to simplify the library code, I would say revert the change, as ~20% regression is quite significant.

Another thing that I don't understand was that on you PR, you did run the microbenchmarks for Mono AOT and didn't see significant change there. But here you were able to see the regression when you run them again. I wonder what you did differently?

It was simplification. I did not want to duplicate all the methods for another time when adding BFloat16. I think it should be fine to use the generic version for Half and BFloat16 since they are less important.

The manual test was on Windows, and the script driven test was on WSL. Maybe the build on Windows is not clean and messed up.

I think in this case there's a small enough amount of code and this is a core enough API that duplicating it is "ok".

But notably this is just another scenario where there's a fairly substantial amount of code that needs to exist per supported T (around 200 lines) and the T we have to support is frequently 2 (byte and char), 3 (float, double, Half; potentially BFloat16 and others in the future), 10 (byte/sbyte, short/ushort, int/uint, long/ulong, nint/nuint), or even the full set of primitives. Generics are the solution to not only avoid this duplication, but also to increase maintainability and reduce the risk of bugs. There's many other scenarios where duplicating the code is not feasible or adds too much risk and so it is not always going to be a viable workaround to ensure that the Mono performance doesn't regress.

It would be great if we could take another look at what it would take to add even basic generic specialization support to Mono and try to prioritize that work as I expect it would have substantial improvements to the ecosystem and likely give Mono some reasonable size improvements on top of that. Even if the feature was scoped to only work for corelib using an internal [MonoSpecialization(typeof(...)] attribute so we could explicitly list the finite set of encounterable T, I think that would provide substantial wins and solve the more immediate problem.

@huoyaoyuan It would be nice to get the PR of reverting merged before Preview7 snap (July 19), if possible.

I would say that the 20% regression in floating number formatting microbenchmarks is acceptable. The scenarios targeted by Mono are very unlikely to be dominated by floating point number formatting. It is not a regression with significant customer impact.

The generic code should be smaller. I would expect that the change is a small improvement for IL-only binary size that is also important metric for scenarios targeted by Mono.

As Tanner pointed out, the patterns used by the offending PR is used in many places throughout the libraries. If Mono is not able to handle it well, it is a much bigger problem that floating point number formatting microbenchmarks. We should be looking at each case individually, but I do not think it makes sense to try to preserve unnaturally written code to prevent regressions at all costs.

It would be great if we could take another look at what it would take to add even basic generic specialization support to Mono

It may help here and there, but I do not think it would fix the structural problem that a lot of new code is leveraging advanced RyuJIT optimizations. I believe that we will need to eventually figure out how to leverage RyuJIT here. It is not feasible to replay the RyuJIT investments in Mono codegens.

Another case is the auxiliary IUtfChar type for UTF-8/UTF-16 unification. It's used much more intensively. Microbenchmark shows that coreclr appears to handle IBinaryInteger well. If mono can also handle it equivalently, switching to public type will help types outside CoreLib, namely BigInteger.

It should be another problem of generic specialization pattern though.

The generic code should be smaller. I would expect that the change is a small improvement for IL-only binary size that is also important metric for scenarios targeted by Mono.

I believe the issue (and would appreciate confirmation from @fanyang-mono or @matouskozak) is that this is hitting the general USG (Universal Shared Generics) paths for Mono and so it actually results in a non-trivial increase to size (see also #104952).

Due to the lack of specialization, the USG paths for value types on Mono also end up being slower and lead to these types of perf slowdowns. To my understanding, MonoAOT also doesn't utilize any logic similar to NativeAOT and so is unable to discern when a given generic will only ever be encountered by a finite set of types, this causes it to generate code to handle any value type rather than the finite set that will actually be encountered for typical scenarios.

The believe is then that having a way to propagate this information to Mono and have it take advantage of that would go a long way towards mitigating these types of regressions.

I believe that we will need to eventually figure out how to leverage RyuJIT here. It is not feasible to replay the RyuJIT investments in Mono codegens.

👍, it is definitely a significant amount of work to mirror optimizations between all the possible backends (RyuJIT, MonoJIT, MonoInterpreter, MonoLLVM, etc). The wins when we have mirrored key optimizations have typically been positive when done, however, and I'd imagine we want to continue targeting key scenarios for the foreseeable future (at least until we are at a point where an alternative is viable), so I'm mostly just trying to call out the places that I believe would have the biggest impact based on my understanding of the problem space.

Yes, it would be good to confirm the root cause.

The USG fallbacks typically introduce much worse regressions than 20%. Given that the regression is relatively small, my assumption was that it is caused by inliner and optimizer limitations.

I will need to analyze to generated code closely to confirm that. Will report back later.

I conducted my investigation based on microbenchmark System.Tests.Perf_Single.ToStringWithFormat(value: 12345, format: "R"). It regressed 26% after @huoyaoyuan 's formatting PR.

The major regression caused by the JIT/code running time of the newly introduced methods highlighted on the right-hand side of the following screenshot.

Those methods are all generic methods which are not AOT'ed. Mono doesn't have tiered JIT. I am not sure what kind of optimizations we could add to Mono JIT to make these extra methods calls go away. @lambdageek Feel free to comment, if you have more thoughts on this.

Some of the other functions in there are also fairly hot.

Cases like new Vector<byte>, SpanHelpers.Fill, Unsafe.Bitcast, etc. Many of them are intrinsic to Mono, so it's interesting that they are being left in as calls, right?
