2023-09-23	feat(ext/web): use readableStreamDefaultReaderRead in ↵	Matt Mastracci
	resourceForReadableStream (#20622) We can go one level down in abstraction and avoid using the public `ReadableStream` APIs. This patch ~5% perf boost on small ReadableStream: ``` Running 10s test @ http://localhost:8080/ 2 threads and 10 connections Thread Stats Avg Stdev Max +/- Stdev Latency 148.32us 108.95us 3.88ms 95.71% Req/Sec 33.24k 2.68k 37.94k 73.76% 668188 requests in 10.10s, 77.74MB read Requests/sec: 66162.91 Transfer/sec: 7.70MB ``` main: ``` Running 10s test @ http://localhost:8080/ 2 threads and 10 connections Thread Stats Avg Stdev Max +/- Stdev Latency 150.23us 67.61us 4.39ms 94.80% Req/Sec 31.81k 1.55k 35.56k 83.17% 639078 requests in 10.10s, 74.36MB read Requests/sec: 63273.72 Transfer/sec: 7.36MB ```
2023-09-16	perf: improve async op santizer speed and accuracy (#20501)	Luca Casonato
	This commit improves async op sanitizer speed by only delaying metrics collection if there are pending ops. This results in a speedup of around 30% for small CPU bound unit tests. It performs this check and possible delay on every collection now, fixing an issue with parent test leaks into steps.

2023-08-22	fix(ext/web): better handling of errors in resourceForReadableStream (#20238)	Matt Mastracci
	Improves error handling when the Resource is closed in various phases of the ReadableStream. Ensure that we send a consistent `cancel` reason.
2023-08-17	feat(ext/web): resourceForReadableStream (#20180)	Matt Mastracci
	Extracted from fast streams work. This is a resource wrapper for `ReadableStream`, allowing us to treat all `ReadableStream` instances as resources, and remove special paths in both `fetch` and `serve`. Performance with a ReadableStream response yields ~18% improvement: ``` return new Response(new ReadableStream({ start(controller) { controller.enqueue(new Uint8Array([104, 101, 108, 108, 111, 32, 119, 111, 114, 108, 100])); controller.close(); } }) ``` This patch: ``` 12:36 $ third_party/prebuilt/mac/wrk http://localhost:8080 Running 10s test @ http://localhost:8080 2 threads and 10 connections Thread Stats Avg Stdev Max +/- Stdev Latency 99.96us 100.03us 6.65ms 98.84% Req/Sec 47.73k 2.43k 51.02k 89.11% 959308 requests in 10.10s, 117.10MB read Requests/sec: 94978.71 Transfer/sec: 11.59MB ``` main: ``` Running 10s test @ http://localhost:8080 2 threads and 10 connections Thread Stats Avg Stdev Max +/- Stdev Latency 163.03us 685.51us 19.73ms 99.27% Req/Sec 39.50k 3.98k 66.11k 95.52% 789582 requests in 10.10s, 82.83MB read Requests/sec: 78182.65 Transfer/sec: 8.20MB ```
