We have recently been working on optimising the speed of the ONE platform, especially improving the page load time for external users with restrictions applied.
Here you can see some comparisons of the reduction of load time for external users:
97% reduction of Programme page loading series information* (from ~30s to ~1s)
67% reduction of adding programmes to a list* (from ~6s to ~2s)
94% reduction in loading of the Video carousel series filter (from ~50s to ~3s)
80% reduction in loading of series listing (from ~50s to ~10s)
*Please note that if a series has less series information, the active requests will be faster!
