On top of https://github.com/astral-sh/puffin/pull/947, we can also box `PrioritizedDistribution`. In a simple benchmark, this seems to slightly improve performance when comparing only this commit to main, even though the benchmark is too noisy to establish significance: ``` $ hyperfine --warmup 30 --runs 300 "target/profiling/main-dev resolve meine_stadt_transparent" "target/profiling/puffin-dev resolve meine_stadt_transparent" Benchmark 1: target/profiling/main-dev resolve meine_stadt_transparent Time (mean ± σ): 83.6 ms ± 2.0 ms [User: 77.7 ms, System: 20.0 ms] Range (min … max): 81.4 ms … 98.2 ms 300 runs Warning: Statistical outliers were detected. Consider re-running this benchmark on a quiet system without any interferences from other programs. It might help to use the '--warmup' or '--prepare' options. Benchmark 2: target/profiling/puffin-dev resolve meine_stadt_transparent Time (mean ± σ): 80.8 ms ± 2.2 ms [User: 75.4 ms, System: 19.5 ms] Range (min … max): 78.6 ms … 98.6 ms 300 runs Warning: Statistical outliers were detected. Consider re-running this benchmark on a quiet system without any interferences from other programs. It might help to use the '--warmup' or '--prepare' options. Summary target/profiling/puffin-dev resolve meine_stadt_transparent ran 1.03 ± 0.04 times faster than target/profiling/main-dev resolve meine_stadt_transparent ``` The effect on type sizes however is considerable ([downstack PR](https://gist.github.com/konstin/38e6c774db541db46d61f1d4ea6b498f) vs. [this PR](https://gist.github.com/konstin/003a77fe7d7d246b0d535e3fc843cb36)): ```patch --- branch.txt 2024-01-17 14:26:01.826085176 +0100 +++ boxed-prioritized-dist.txt 2024-01-17 14:25:57.101900963 +0100 @@ -1,19 +1,3 @@ -9264 alloc::collections::btree::node::InternalNode<pep440_rs::version::Version, distribution_types::PrioritizedDistribution> align=8 - 9168 data - 96 edges - -9264 alloc::collections::btree::node::InternalNode<pep440_rs::Version, distribution_types::PrioritizedDistribution> align=8 - 9168 data - 96 edges - -9168 alloc::collections::btree::node::LeafNode<pep440_rs::version::Version, distribution_types::PrioritizedDistribution> align=8 - 9064 vals - 88 keys - -9168 alloc::collections::btree::node::LeafNode<pep440_rs::Version, distribution_types::PrioritizedDistribution> align=8 - 9064 vals - 88 keys - 8992 tokio::sync::mpsc::block::Block<hyper::client::dispatch::Envelope<http::request::Request<reqwest::async_impl::body::ImplStream>, http::response::Response<hyper::body::body::Body>>> align=8 8960 values 32 header @@ -74,10 +58,23 @@ 40 __tracing_attr_span 64 variant Unresumed, Returned, Panicked +5648 {async fn body@crates/puffin-client/src/registry_client.rs:224:5: 224:30} align=8 + 5647 variant Suspend0 + 5576 __awaitee align=8 + 40 __tracing_attr_span ```
