[v0.26] contentutil: avoid defaulting to ReadAt for fetch - #6367
Merged
Conversation
Containerd v2.2 updated the ReadCloser returned from Fetcher to implement ReadAt, but it works by making a separate HTTP request for each read. This means lots of requests depending on the buffer size used by copy. In containerd content pkg buffer is 1MB. Signed-off-by: Tonis Tiigi <tonistiigi@gmail.com> (cherry picked from commit d5b7dda)
