This Kura patch improves artifact download speed and reliability for large caches.
- Artifact downloads now use a Linux kernel fast path (splice by default, sendfile optional) for eligible HTTP/1 artifact GET requests. The accelerator keeps the same public port, only takes over after authorization and file resolution, and falls back to the regular Hyper path when the fast path is unsafe or at capacity.
- Public latency is now measured when a response is ready to start streaming, so large healthy downloads do not over-throttle replication. Public-inflight accounting now covers the full lifetime of fallback HTTP streams as well.
- Replication bandwidth limiting is active by default and backed off under public load or elevated latency. Set
KURA_REPLICATION_BANDWIDTH_LIMIT_BYTES_PER_SECOND=0to disable it.
