Description

Display can be quite slow with lots of nodes.

with 4500 nodes, on a very loaded system the resquest takes 3 seconds (750 ms of node info (3 times 250M ms, 300 ms of compliance, 700 ms of lift, you can add runs and response making to go to 3 seconds) whcih procude 6mb of data, (compressed to 250kb) but this gives a lot of data to handle on browser side (extraction + datatable handling data) could block the browser for and additional 2-3 secondes or more

We should reduce the amount of data =>
  • remove explanation of global mode, replaced by a simple string=
  • remove system compliance Array
  • reduce size of compliance array (not be an object containing value but be an array, lots of data

with this it reduce to 2mb

Also we can add the deferRender option to only render the visible Rows instead fo the whole table, this will delay the computation to when we chnage page but it costs nothing (rendering 25, 100 500 rows is really faster than rendering 4500)
