The Test PLA extends this idea further. It operates asynchronously with respect to the sequencer. After a protection test fires, the PLA needs time to evaluate and produce its redirect address. Instead of stalling, the 386 allows the next three micro-instructions to execute before the redirect takes effect -- and the microcode is carefully written to use these delay slots productively. This is tremendously confusing when reading the microcode for the first time (huge credit to the disassembly work by reenigne). But Intel did it for performance.
If the transform's transform() operation is synchronous and always enqueues output immediately, it never signals backpressure back to the writable side even when the downstream consumer is slow. This is a consequence of the spec design that many developers completely overlook. In browsers, where there's only a single user and typically only a small number of stream pipelines active at any given time, this type of foot gun is often of no consequence, but it has a major impact on server-side or edge performance in runtimes that serve thousands of concurrent requests.

BYOB (bring your own buffer) reads were designed to let developers reuse memory buffers when reading from streams, an important optimization intended for high-throughput scenarios. The idea is sound: instead of allocating new buffers for each chunk, you provide your own buffer and the stream fills it.，更多细节参见服务器推荐
