The chunk size used for downloading images was 64KiB for some time. That is okay for relatively small images but the client side of CPU can be a bottleneck especially for large images. Bump the default chunk size from 64KiB to 1MiB so we can use the client side CPU more efficiently. [64KiB chunk size - current] INFO cinder.image.image_utils Image download 1907.35 MB at 68.61 MB/s -> ~ 549 Mbps [1MiB chunk size - patched] INFO cinder.image.image_utils Image download 1907.35 MB at 132.10 MB/s -> 1,057 Mbps Closes-Bug: #2020139 Change-Id: I8b6e19621fc989526b02319d88fcfde88a17eee0 (cherry picked from commit 7d78cc4b9d43f5abdf8c7fa05e37ab8c8122c325)

Python bindings to the OpenStack Images API
This is a client library for Glance built on the OpenStack Images
API. It provides a Python API (the glanceclient module) and
a command-line tool (glance). This library fully supports
the v1 Images API, while support for the v2 API is in progress.
Development takes place via the usual OpenStack processes as outlined in the developer guide. The master repository is in Git.
