Constants

const BufferSize = 1 << 20

BufferSize balances stream-call reduction against concurrent memory use. At the benchmark's 10 peer serves plus 6 local downloads, a fully busy agent can hold at most roughly 16 MiB of copy buffers.

Functions

func CopyN 

func CopyN(dst io.Writer, src io.Reader, size int64) (int64, error)

CopyN copies exactly size bytes. It fills each pooled chunk before writing, reducing containerd ReaderAt streams and downstream Writer calls while preserving partial bytes and the original read error on interruption.
