UI becomes super slow with > 1K annotations #3875

@H-Shafiei , which version of CVAT do you use? Could you please fill issue template? |
Hey, I'm having the same issue while annotating on cvat.org. I'm reaching 5000 polygon annotations over 3 images with resolutions around 10000x5000. My actions before raising this issue
Expected BehaviourUI should be able to handle a large number of annotations on a single image without making every action delayed. Current BehaviourLoading an image with around 3000 polygon annotations causes multiple "Page unresponsive" prompts, before said image loads. After an image is loaded every action (hovering over UI elements, padding or zooming the image, editing or creating a new annotation) is delayed by 2-5 seconds. Possible SolutionAfter detecting a drop in responsiveness (long image load time, a large number of annotations, or the time it takes to perform certain actions) present a user with a way of increasing responsiveness by allowing the user to choose a smaller part of an image that he currently wants to work on which could work as follows:
ContextI'm trying to annotate stars on photos made by astronomic telescopes that are usually large files with thousands of visible stars. Your EnvironmentI'm using the cvat.org with Brave browser. I assumed that hosting CVAT locally would not provide any improvement however, let me know if I'm wrong. |
Hi, any update on this issue? CVAT becomes super slow when selecting the label if I have few thousands of label candidates. |
Hello, I am also wondering if there is any update on this issue? I regularly deal with images that require thousands of labels and after about 700-800 there is a noticeable lag between every single action (selection, creation, deletion, resizing, moving, etc.), sometimes as a large as whole seconds. As of this moment, I use the latest version in the develop branch. |

Looks like the way around this is to take a dataset, and instead of uploading it whole to cvat, write custom code to chunk the dataset into separate tasks and organize it as its own project Edit:

What could be the problem |
That is not related to this issue. |
Hi
I have a job containing 2 images which I start to annotate with the polygon tool. After annotating more than 800 polygons per image, the UI gets extremely slow. How can this be fixed?
Thanks
