I am running a shiny app on a local server: https://www.zmbp-resources.uni-tuebingen.de/timmermans/plant-single-cell-browser-leaf-atlas/
I have an issue with the long loading time when the app is accessed from a PC for the first time. It takes about 40s to load it in a browser. Then, when you let the app load completely and when accessed the second time, it shows up immediately. I tested it with Chrome and Firefox on three computers.
I believe that it is because the browser initially caches a lot of data. The app itself does not do any intensive calculations. Though I may be wrong.
My question is:
Is there a way how to reduce the time of initial data caching by, for example, reducing the amount of the data to be locally cached?
