> - Nextcloud (aka Collabora) Office is very slow if you want to actually work collaboratively with it (no matter the power of your Collabora server) – unfortunately it's no match for Google Docs or Office 365

What about onlyoffice ?

Can you confirm your experience comes from a nextcloud instance and a collabora instance on two different servers ? What was the bottleneck ? Network traffic ?

It's been a while since I used OnlyOffice, can't really speak to its performance.

I think mostly the sluggishness comes from some input delay in the browser. When you open a Collabora Calc document and select any random cell, it just takes a couple of hundred miliseconds till the cell is actually selected. I can reproduce this with brand new instances, no matter how beefy the server is.
