I haven't seen any such performance degradation. However
In Classic UX unless the model gets refreshed and pulled up we weren't able to login and see the dashboard. There was a delay before we could even see the dashboard (due to inactivity in the model)
In New UX we can login to the app without opening the model but it doesn't change the fact that every page takes sometime to be up and live (due to inactivity in the source models because in New UX app could be formed of multiple models)
Barring this I haven't experienced performance delay.
I just wanted to second your findings. I would say that it's hard to measure the difference of dashboard vs page opening time, but refreshing the same dashboard vs page and data input definitely feels laggier in the new UX compared to the classic. Definitely it gets stuck for a longer time a bit more often.
It would be great if we had some official performance figures from Anaplan to rule out network issues or anything else that could influence this.
Yes, definitely having the same performance issue with the NUX in comparison to Old UX. Much more apparent in Dashboard pages compared to Worksheet pages.
Noticed that bigger the table with increased cells compounds the performance degradation to the point where you just can't input without waiting 5-10 seconds every input.
Also noticed that including Field cards on the page impacts the performance when opening the page.
After the creation of beautiful NUX, due to this performance issue, we are now in a dilemma if we should really bring NUX into production.
We have tried various different build to improve the performance but no luck so far. We even went far as disconnecting all the referencing from another module to see that will improve. It kind of helped though I feel this performance issue is got to do with how the backend website coding is built and interaction between the frontend to the database in that there seems to be no buffer when entering the data, therefore, there is always a delay while the inputted data flows back to the database.
Live updating of inputs is good when you want to see instantaneous changes to other models or charts on the same page but it impacts the performance adversely.
Hope there will be enhancements soon as this issue jeopardises faster business take up of NUX.
