Hi Sam,
In case its useful for comparison I looked at Swift SSL performance in
general a while back:
https://region-a.geo-1.objects.hpcloudsvc.com/v1.0/AUTH_19cbcca3-a4b8-4b90-9332-c9bffd02285f/public_referenced/swift_perf6.pdf
I didn't see pound hurting performance as much as you did, but our configs
may have been different.

PS
There's currently some work being done to allow the
Glance client to disable SSL compression on a per connection basis:
https://blueprints.launchpad.net/python-glanceclient/+spec/ssl-connect-rework
If this gets merged it will cover the glanceclient -> glance data path but
not the glance -> swift part. (With a bit of luck that may get added later.)

OK we changed to use nginx as opposed to pound and got a huge increase in speed.
With taking glance out of it and talking directly to swift an image took 1m38s
to download with pound in front.
With nginx this took just 5s not sure what is wrong with pound, we haven't
changed any settings for pound or nginx.

Hi,
We've recently enabled ssl on our swift-proxy and now glance is incredibly
slow. I've read some stuff about disabling zlib compression etc.
Has anyone got a good fix for this?
We're using Ubuntu 12.04
Cheers,
Sam
