Comment 19 for bug 620789

What I would be most interested in learning is why KDE3 can deal with huge text files so much better than KDE4. Surely something can be done?

I agree that multi-GiB files are not of much concern, but text-format databases and the like regularly reach into the dozens or hundreds of megabytes, and should be considered.

Even if it's a solution as clunky as a checkbox upon open, or auto-detect, for "large file mode".
