[Bug] Loading speed of ultrasound (US) study. (Videos or Sequences.)

[VetsImaging]

Describe the Bug

Now, I am using v3.8.0 (release) , connecting with ORTHANC on my local Windows11(pro) . When we play ultrasound (US) study (videos or sequence), it doesn't play smoothly. The loading speed seems slow. After 30 seconds ~ a few minutes, it play smoothly. Is there any solutions to play US study more smoothly, without waiting for a few minutes ? I have uploaded screen capture videos as below ; https://youtu.be/zDZNy25YMdk?si=o7QdcdbapXdxY6hb

As additional detail information, I have posted this issue to Discourse of ORTHANC because I suspected the loading speed depends on ORTHANC performance. Loading time of the ultrasound sequence file ; https://discourse.orthanc-server.org/t/loading-time-of-the-ultrasound-sequence-file/4714/1 But they concluded that the loading speed is most likely depends on OHIF rather than ORTHANC.

Steps to Reproduce

1. git clone https://github.com/OHIF/Viewers.git
2. cd ./Viewers
3. switch branches/tags to v3.8.0 (release)
4. yarn install
5. yarn run dev:orthanc
   • We don't modify any file in this repo.
   • ORTHANC Version : 1.12.3 (installed by OrthancInstaller-Win64-24.5.1.exe) Configuration files : default (not changed )
   • Specifications of my local computer is as below ; 　CPU : intel core-i7 13700H 　RAM : 16GB 　Storage : SSD 1TB

The current behavior

When we play ultrasound (US) study (videos or sequence), it doesn't play smoothly. The loading speed seems slow. After 30 seconds ~ a few minutes, it play smoothly.

The expected behavior

When we play US videos, it play smoothly. If it takes a time to loading US videos, it is better for user to show "loading bar" as v2.
