We benchmarked native WebStream pipeThrough at 630 MB/s for 1KB chunks. Node.js pipeline() with the same passthrough transform: ~7,900 MB/s. That is a 12x gap, and the difference is almost entirely Promise and object allocation overhead."
The rapier crate also published a blog post highlighting a major change to its underlying math engine, in its 0.32.0 version so I asked Opus 4.5 to upgrade to that version…and it caused crashes, yet tracing the errors showed it originated with rapier itself. Upgrading to 0.31.0 was fine with no issues: a consequence of only using agentic coding for this workflow is that I cannot construct a minimal reproducible test case to file as a regression bug report or be able to isolate it as a side effect of a new API not well-known by Opus 4.5.
