Title:
https download performance significantly worse in precise than lucid
Status in openssl package in Ubuntu:
Incomplete
Status in wget package in Ubuntu:
Invalid
Bug description:
In Canonical's openstack installation, I noticed during publishing
images that downloads on lucid seemed to occur faster than I could do
the same download on precise.
$ wget https://cloud-images.ubuntu.com/precise/current/precise-server-
cloudimg-amd64-disk1.img -O /dev/null
In the above, cloud-images.ubuntu.com is located very close to the
instance running, such that on lucid I routinely get > 40M/s.
However, on precise I routinely top out at 10M/s, with the highest
I've ever seen at 19M/s. I once saw 49M/s on lucid.
very strangely (and thus making this harder to isolate), if I change
'https' above to 'http', both lucid and precise download in the
65-80M/S range.
Ie, https download is significantly slower in precise compared to
lucid.
One likely unrelated point, in EC2, using the url
https://ubuntu-data.s3.amazonaws.com/ebs/ubuntu-images/ubuntu-lucid-10.04-amd64-server-20100427.1.img.tar.gz
from a m1.large instance, lucid and precise are both getting in the 25-30M/s
range. With the http url they both get in the 40M/s range.
Ie, there seems no real difference on EC2.
I do realize that this is difficult to isolate, and it is even
possible that my results are affected by other guests on the same host
or load on the http server at that time. However, the results have
been very consistent over multiple days, over new instances.
