In tests, it looks good, it cHashD better than other analogs in speed. But in the real application I see a noticeable performance drop.

I use methods add, item, exist, removeall, type of comparison-vbbinarycompare.
My program works with a lot of text information and uses the dictionary to find duplicate rows (exist method).
My app - https://github.com/ADIAProject/DIA

The program need the driver packages (DP*.7z) - can be downloaded:
