Reduce time between image labeling

[blakespace]

When a label is finished. It takes some time to move to the next image. I assume this is due to the next image in a labelers queue being loaded? Or is this due to some network request occur upon submit that is slow?

This inbetween task time can take 1-2 seconds. That means for every 1000 tasks, ~16 minutes is being wasted by a labeler just waiting for the next task to load up. Can this be sped up somehow?

When I've created small personal labeling tools, I know what image is next in a user's queue and prefetch it for them so that as soon as they click submit the next image is available for view. If that image is high resolution, I load a low res image first followed by a higher resolution image. Especially when we are using a cloud storage provider for our images prefetching these images could save a lot of time.

Could something like this be implemented in Label Studio?

确实，要好几秒，其他方面都挺好用的，这一点就很影响效率
