[Bug] Improve Performance of OHIF renders using DICOMJson as a data source

[highoncarbs]

Describe the Bug

Right now , we are using OHIF 3.7 using DICOMJson as a datasource, but the loading time is quite slow for large studies.
Is there anything that can be done to speed this up or make it more efficient ? via configs or via parallelizing all the dicom file URLs ?

Steps to Reproduce

use any large DICOMJson data source

The current behavior

The loading time is slow for users

The expected behavior

Make the dicomJson data source faster to render for clients

OS

Windows 11. Edge - Chrom

Node version

20

Browser

Edge, Chrome Latest

Version 3.7 is outdated, and I don't plan to make further improvements. Please try version 3.9, and if the issue persists, we can address it.

We also tried with the official OHIf 3.9 deployment - still the same result. Is there anyway to speed this up or make this more efficient

Not really, you can use wado, instead of dicom json https://docs.ohif.org/configuration/dataSources/dicom-web
