Hello HaoLiu,

Can you tell us, how are you loading the images? is it through local storage? or importing through UI? or through SDK? the resolution of the images? labeling interface? could help us reproduce the problem

Hello HaoLiu,

tried local storage and ceph s3, the images resolution is 1080P. We have this problem in own developed label tool before, we solve it by preload some images into redis when labeling, so I am wondering whether label studio have the same ability

Facing a similar issue when loading audios from S3. It can take tens of seconds to load an audio, and perhaps a similar time to label it, so preloading the next sample would greatly speed things up.

Loading is triggered when scrolling to the bottom of pre-loaded tasks. An environment variable to adjust when it loads the next page or two of tasks would be fantastic. For instance, instead of triggering when scrolling to the bottom, it triggers when 5 or 10 tasks to the bottom. Adjusting how many tasks are preloaded in a batch would be a nice feature as well.
