Walkthrough

The configuration logic for the rate limiter was updated so that when the "rate-limiter-auto-tuned" option is enabled, the rate limiter bandwidth is forcibly set to 10 GB/s, overriding any previously set or default value. No changes were made to public interfaces or exported declarations.

Poem

A whisk of code, a clever tune,
Bandwidth soars beneath the moon.
Ten gigabytes now set with flair,
No more stalls to cause despair.
With every hop, the bytes will flow—
This rabbit’s proud to see it so!

Support

Need help? Create a ticket on our support page for assistance with any issues or questions.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.
