However, I recently switched from Google Chrome to Firefox, and suddenly Collabora has become hugely slower. It’s not a server-side issue or a load problem on my computer, because when I switch between viewing the same document on the same computer in Chrome versus Firefox, Collabora is way more responsive in Chrome. I see the same behavior on both Linux (Pop!_OS) and macOS.
I can see the issue with both the ODT editor (docs) as well as the ODS editor (spreadsheets), but it is by far more pronounced with spreadsheets. I have taken a screen recording to demonstrate the issue. The difference in responsiveness is most obvious with the effective framerate I get when scrolling. Compare Firefox on the left with Chrome on the right.
I found a previous forum post about Collabora performance, I am not sure if it is the same issue though, as there is no reference to browser choice being relevant: Collabora & NC19 - Slow Performance
Anyone seen this before? Is there any workaround or configuration change I can make to improve Firefox support?
Happy to provide any relevant diagnostic information or do debugging on my end. In case this issue has never been seen before, I can also create a publicly editable spreadsheet on my instance so that you can see for yourself.
some time ago there was a (German) post regarding slow scrolling in Calc with FF.
I’m using FF all the time and I don’t feel editing is slow somehow in my system (official Docker image with separate CODE). Starting the docs takes few seconds but once it’s running editing feels fluid, I would say comparable to native apps… In my system I didn’t compare FF and Chrome - maybe there is huge difference if I would.
just to have some “numbers” - because slow could be different depending on what you expect. user running on RasPi likely have lower expectations than other with powerful Xeon server… I agree it must be bad sometimes if multiple users report this… but for me it doesn’t look like general issue… my system seems to run smooth enough.
metrics: official Docker Apache image 25.0.2 with separate CODE 22.05 container running on old Core i3 6xxx CPU and magnetic spinning drives
I created an ods sheet with few hundreds of lines and scrolled through it (using FF). see the video attached. This is definitely not a smooth as native app but for me it looks reasonable fast - isn’t it?
Hm… What do we wanna proof here? I doubt that this is an AIO issue since it uses the official components and scrolling works in chromium based browsers. So why not open a bug report on collabora about this since some js library might be the culprit here?
Well… I was going to check it on my personal instance using official docker images to see if it’s the same way… but my Collabora seems to have stopped working.
Anyway, I don’t believe it’s an issue of resources because both of my instances are running on Dell PowerEdge servers with whatever resources they need.
It’s usable, but slow enough that it’s a bit annoying, especially since I live and breathe large spreadsheets that need a lot of scrolling. I tend to just use LibreOffice unless I’m working on something with a colleague.
