tbh the fact that nextcloud is completely unwilling to take after owncloud and implement a high performance golang backend for some of the more core things is really dumb
like. nextcloud performance is absolutely abysmal. it really needs to be better, yet they won't consider moving off of php
and tbh the bad performance is also likely due to architecture reasons rather than just because it uses php, but rewriting portions of it in go also gives you the chance to improve the architecture
