EmEditor is available in both 64-bit and 32-bit builds. As you can see from the examples on right, the 64-bit build runs as much as 16% to 74% faster than the 32-bit build when dealing with very large files. If you use 64-bit Windows, the 64-bit build of EmEditor is absolutely recommended!

Moreover, EmEditor uses various CPU optimizations such as multithreading and SIMD technology such as AVX-512 and AVX-2 to improve the speed of opening very large files, Find/Replace/Filter, parsing CSV, various Sort, Delete Duplicate Lines, and various other operations.
