When trying to load the node list page, i noticed that it was slower than expected: it took 5,5s for 1000 nodes

But out of these 5,5s, only 3 were somehow useful: first get of page, then some ajax JS blocked, and finally the node list, in 2,5s
The actual loading of node list started only after 3,55s, because of the number of round trip to server to check if each ressources were up to date (see network graph below)

To make things worse, sometime browser seems to believe that the ressource changed, and tries to reload the page

This is especially noticable when network is slow
