Slow data loading in Enketo

Hello everyone !

I have a little issue and I’m not sure how to solve it.

We have a long form with 941 questions including 314 in a repeat group.
The reason why it is so long is that a lot of this questions are about the 187 species that we have.

When we collect data, the form does not take too much time on ODK collect but when we try to edit the answers in Enketo form Kobotoolbox web plateform it takes a lot of time to open.

So we were wondering if this could be solved by using our own server instead of the server " Researchers, Aid Workers & Everyone Else" or by reducing the number of species or something else?

Thank you

Fabien
