notable-change
Please suggest a text for the release notes if you'd like to include a more detailed summary, then proceed to update the PR description with the text or a link to the notable change suggested text comment. |
@RafaelGSS maybe too tight with v21 but I think this is quite a notable change that can have impact. |
@nodejs/http |
Can you please include benchmark code and results? |
@rluvaton are you blocking on that? |
No, because of the tight release time but would appreciate in a different pr |

@Trott Can you help landing this? |
@nodejs/tsc needs another approval. The semver major is because it might break clients that make incorrect assumptions about the chunking of responses. |

@ronag can you update the PR to include a description for the blog post? Something easy for users, thank you! |

Avoid splitting chunked responses into multiple parts when corking. This makes a large difference performance-wise on the client side.
Previously when writing to a chunked response Node would create a separate chunk for each call to
.write(...)
regardless whether the response was corked or not. This leads to unnecessary overhead both on the client and server side.This PR fixes this by creating a single chunk for all calls to
write(...)
when uncorking the response.Consider the following example based on https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Transfer-Encoding#chunked_encoding:
Resulting in a response stream looking like this:
After this PR everything is combined into a single chunk when uncorking the response bypassing a lot of unnecessary overhead.
