# Description Adjust the PoV response size to the default values used in the substrate. Fixes #5503 ## Integration The changes shouldn't impact downstream projects since we are only increasing the limit. ## Review Notes You can't see it from the changes, but it affects all protocols that use the `POV_RESPONSE_SIZE` constant. - Protocol::ChunkFetchingV1 - Protocol::ChunkFetchingV2 - Protocol::CollationFetchingV1 - Protocol::CollationFetchingV2 - Protocol::PoVFetchingV1 - Protocol::AvailableDataFetchingV1 ## Increasing timeouts https://github.com/paritytech/polkadot-sdk/blob/fae15379cba0c876aa16c77e11809c83d1db8f5c/polkadot/node/network/protocol/src/request_response/mod.rs#L126-L129 I assume the current PoV request timeout is set to 1.2s to handle 5 consecutive requests during a 6s block. This setting does not relate to the PoV response size. I see no reason to change the current timeouts after adjusting the response size. However, we should consider networking speed limitations if we want to increase the maximum PoV size to 10 MB. With the number of parallel requests set to 10, validators will need the following networking speeds: - 5 MB PoV: at least 42 MB/s, ideally 50 MB/s. - 10 MB PoV: at least 84 MB/s, ideally 100 MB/s. The current required speed of 50 MB/s aligns with the 62.5 MB/s specified [in the reference hardware requirements](https://wiki.polkadot.network/docs/maintain-guides-how-to-validate-polkadot#reference-hardware). Increasing the PoV size to 10 MB may require a higher networking speed. --------- Co-authored-by: Andrei Sandu <54316454+sandreim@users.noreply.github.com> (cherry picked from commit 0c9d8fe)
