Ian Jackson (ijackson) wrote : too many http transactions make everything too slow

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.
