Synchronization speed

Tried out Penpot when we were looking into which tools we wanted to use for both UX and UI design work on my team a while back, and there was one big issue that still doesn’t seem to be resolved: Synchronization speed. Right now, the time it takes between when one user makes a change and the other user sees it is quite slow. Opening two windows side-by-side, just drawing or moving a simple rectangle can take 2-3 seconds to show in the other window. In other apps we’ve used, this happens much faster, and we found that this lag/delay to be very frustrating and awkward when we want to actively collaborate on a document at the same time, for example when whiteboarding.

Would be interesting to know what the biggest factors are that lead to this situation and the viability of improving it!
