Description
On page with large datasets I have noticed that the page takes an incredible time to load. 25 seconds spent making javascript work at 100% CPU on my mac desktop on the prototype site.
Some of these issues can be solved by paging and so on, but I think some analysis/fixes of the underlying causes should be done and have benefits elsewhere - espsecially if this is going to be a common pattern of development.
Steps to reproduce:
- Login as student
- Visit 'my learning plans' dashboard block
- Click on large learning plan
Expected results:
- The page renders instantly (no user-notiable lag)
Actual results:
- The page takes about 25 seconds to render - the time is spent in javascript, using 100% CPU time of my 2.6Ghz Core i7
