I was trying to use Launchpad while also using my internet connection for an rsync. RTT to launchpad.net from my workstation is around 550ms right now.
I noticed that things were very slow, so I timed one of my page loads. I started at:
https://launchpad.net/distros/ubuntu/+search?text=openoffice.org
and clicked on `"openoffice.org2" in Ubuntu' to take me to
https://launchpad.net/distros/ubuntu/+source/openoffice.org2
That page took 16 seconds to load. My browser and setup are otherwise normally reasonably fast; my workstation is an AMD Athlon 2400+ with 1.5Gb of RAM.
If more of the page was cacheable then the number of sequential transactions would be reduced. Also, if the page were simpler it would be faster.
As a comparison,
http://www.kyradesign.co.uk/sites/ceasite/pages/cea.html
takes 5 seconds with shift-reload to force reloading of everything. Normal navigation to pages already seen is instantaneous. |
Quoting Andrew:
"...It's not so much the intrinsic overhead of SSL, it's that browsers typically don't cache resources served over https. This has the unfortunate result that linked images, css and javascript are redownloaded everytime. At the same time, browsers complain if you try to link to things like images at http URLs from https pages, with big scary warnings that "some parts of this page may be insecure."
The best solution I know of is to only use https for the login form, because that transmits a password, and let everything else be in the clear." |

too many http transactions make everything too slow |
Serving everything under SSL causes slowdown |
