However I do not understand what exactley you want to tell us with this post. I assume you want people to post their details, so you can compare your performance to theirs. But to be able to make a reasonable comparison, too many details are missing in your post, which can affect these results…
Which Office? OnlyOffcice or Collabora?
How is this office installed? Integrated app, Docker, Linux packages…
On the same server or on a separate server?
Which VPS provider?
How fast is your internet line?
Which web server are you using, and how is it configured?
What PHP version are you using, and how is it configured?
What memory cache are you using, and how is it configured?
I have NC and Collabora running as Docker on i5 (~2014) with 16GB total RAM. docker and containers are stored on magnetic drive. I have around 8-9 sec to create new .odt or .odc file… (when Collabora is warm - the very first docs after long inactivity takes additional ~10sec)
