302 redirects are affecting performance #512

Closed gimick closed 11 years ago

gimick commented 11 years ago

When the webserver is tested with 10 client connections, the exercise dashboard is taking a significant time to load: (typically between 10 and 40 seconds).

Root of this issue? the webserver appears to process all icons twice? :

A retest with the images path hacked to /static/images instead on /images gives page load times of less than 1 second.

The redirect is in kalite/main/urls.py The resource file with the /images/ links is kalite/static/data/maplayout_data.json other /image resources are referenced in kalite/static/js/kmap-editor.js

(SeleniumClient test step is neadd2_1 and nesub2_1)

Can this be changed to not generate a 302 status?
