One core in CPU usage rate remains at 100% for a long time, causing serious delays in new blocks and forks #27623

Is there an existing issue for this?

• I have searched the existing issues

Current behaviour

We are the technical team from AntPool. We found that when the Bitcoin wallet node processes the process message recently, the single-threaded CPU 100% causes block parsing delays, resulting in serious technical failures. Our version number is the latest version 24.0.1。 Not only antpool, we also asked other mining pools and found this problem. This will lead to increasingly serious orphan blocks and forks.

Expected behaviour

Run ProcessMessage with multiple threads to reduce the performance problem of CPU single-thread ProcessMessage. Or are there other configurations that can alleviate this problem?

Steps to reproduce

Run the wallet, synchronize to the latest height, and then observe the CPU usage. You can see that there is a single-core CPU usage that remains at 100% for a long time

Hello @huzhenyuan, thank you for the report.

v24.1, with mitigations for the issues you are seeing, should be available shortly.

thanks @willcl-ark, can you edit you comment and point to the relevant mitigation PR/issues.

@huzhenyuan Thanks for reporting. As mentioned, Bitcoin Core version 24.1 will be available shortly, and contains some mitigations for the issues you are seeing. I'm going to close this issue for now, as similar/related-to #27586.

Are you not running any code to submit blocks across multiple bitcoin daemons around the globe quickly such as redundant nodes using the old FIBRE patchset?

@huzhenyuan v24.1 is now available: https://github.com/bitcoin/bitcoin/releases/tag/v24.1.
