Hi glance experts,
I'm using the following code to download a glance image:
``` from glanceapi import client ... glance = client.Client(GLANCE_API_VERSION, session=sess) ... with open(path, 'wb') as image_file: data = glance.images.data(image_id) for chunk in tqdm(data, unit='B', unit_scale=True, unit_divisor=1024): image_file.write(chunk) ```
And I get a speed around 3kB/s. It would take months to download an image. I'm using python3-glanceclient==3.6.0. I even tried: ``` for chunk in tqdm(data, unit='B', unit_scale=True, unit_divisor=1024): pass ``` to see if the bottleneck was the disk I/O, but didn't get any faster.
In the same environment, when I use the glance CLI instead:
``` glance image-download --file $path $image_id ``` I get hundreds of MB/s download speed, and it finishes in a few minutes.
Is there anything I can do to improve the glanceclient performance? I'm considering using subprocess.Popen(['glance', 'image-download', ...]) if nothing helps...
