I have two CSV files that only differ in the date format: YYYY-MM-DD HH:MM:SS vs. M/D/YYYY HH:MM.
KDiff3 takes 25 seconds to compare these files and freezes as seen in the screenshot.
CompareIt! does the job in half a second.
Meld never finishes, and BeyondCompare thinks files are compeletely different. Can KDiff3 do better?
SmartSynchronize takes 4.5 seconds, and Diffuse 1.5.
Kompare chokes.
And here's a blog post summarizing the state of Linux diff tools performance. Pretty appalling.
