Did you observe performance improvements using `@Stable` on the `cancel` field? It's really hard to predict in the abstract (since the default value of the field will be read in proportion to the number of elements until the stream is cancelled). ------------- PR Comment: https://git.openjdk.org/jdk/pull/18625#issuecomment-2043218633
