Performance issues on large pages. Tried the recommendations.

Hi there!

Long time user here. Description of my issue: performance is bad on my large board (currently around 1300 objects). It’s worse on Firefox than Chrome (firefox: the zoom and dezoom is really bad). Both equally are bad when it comes to adding a new object or editing text, with a serious 0.5 to 1sec freeze.

I did read the thread about performance, and the possible solutions. Cleared cache, and reviewed the image sizes. For info, I do use a lot of tiny images, and made sure to flatten in small size most of them.

My question is: I tried using synced groups in an attempt to lower even more the memory usage (my train of thought is: if I use one image and it’s instanced several times and synced, in theory the memory usage, or at least the bandwidth shall be only for the one image). Turn out the gains are minimal or nonexistent.

At this point, I have no real solutions. Except maybe slicing parts of that board into another board, flattenning one JPG file out of it, and importing it again?…. if a cluster of 200 objects become one JPG file, that should help… it just sounds VERY cumbersome and unpractical for an app that is about fiddling and moving things around, and I can’t realistically do this for a daily workflow.

Another idea/suggestion I tried: using the system emoticons instead of loading up images. The results are inconsistent from one computer to another, but in theory it shall be lighter? Again, didn’t see much of a difference.

I’m open to any suggestion. Did anyone here tried other solutions?

Otherwise I’ll just join the bandwagon of users being mad about the overall performance of Miro. I agree that adding AI is kinda pointless in terms of real value for your users versus providing a good reliable service. I’ve read that 4 engineers were on this? That was in a comment from the team from last year. Hopefully a rework in on the way?

Hi ​@Mathieu Roth  — thanks for the detailed breakdown, and I hear you. It sounds like you’ve tried all the right things (flattening images, synced groups, emojis, etc.), and I agree that breaking up the board isn’t ideal for daily work.

 

You might also want to reach out to support for help specific to your setup.

 

Thanks again for sharing your experience — it helps the whole community!
