Comparing two large files keeps loading forever

[perigozin]

Does this issue occur when all extensions are disabled?: Yes/No

Yes

Software version:

• VS Code Version: 1.90.2
• OS Version: Windows 11 23H2

Steps to Reproduce:

1. Select two somewhat large files to compare
2. Wait indefinitely

Additional context:

• I'm trying to compare two plain text files that have around 30.000 lines (URLs) each. It keeps loading as if it was doing something but it never reaches the end (I waited a few hours just to see if it would finish).
• VSCode keeps using 10~15% of CPU while it's loading the comparison until I close the tab manually (which is weird, I would've thought it would be using 100% or something). RAM seems unaffected.
