[934556826]

Describe the Bug

The stackContextPrefetch.enable method loads dcm files very slowly in Chrome and Edge browsers on Windows, but very quickly in Firefox browser;
It also loads very quickly on my iOS phone, I can rule out the possibility of network speed issues

Steps to Reproduce

"@cornerstonejs/core": "^2.15.4"

Use wadouri loader and use stackContextPrefetch.enable to load the entire Series, csEnums.Events.IMAGE_LOADED callback, count the number of dcm that have completed loading

The current behavior

chrome took 18 seconds

001.mp4

FireFox took 6 seconds

002.mp4

The expected behavior

Restore loading speed

OS

windows 11

Node version

18.17

Browser

Chrome 131.0.6778.265; FireFox 134.0.1

Thanks for your reply. I have downloaded the latest version of Chrome Canary, and the loading speed is still very slow; I also noticed that even if it is loaded twice, reading the DCM file in the network cache is still very slow.
