label studio slowes down when importing OCR preannotations

Hello,

Following [this post ](https://labelstud.io/blog/Improve-OCR-quality-with-Tesseract-and-Label-Studio.html), I converted my OCR output and were able to successfully import them and see the document and bounding boxes in label studio. I am importing bounding box for 10 images and and each image has between 700-800 bounding boxes. Once I open an image to annotate and look at the bounding boxes my browser slows down significantly and does not let me annotate data properly.

I have tried latest versions of Firefox and Chrome. Although Chrome was slightly faster, still it is very slow that I cannot annotate data properly.

Do you have any recommendations or solution for this scenario?

Thank you
