Remove Newline Characters speed

[sky]

EmEditor v16.9.0 beta 4, Windows 10 (64-bit) 16GB RAM

Test 100,000 lines of below, replace all “^\n” with “”. Result: 50000 strings were replaced. (1 threads, 2.65 seconds.)
But, test 500,000 lines of below, replace all “^\n” with “”. Result: 250000 strings were replaced. (1 threads, 64.12 seconds.)
The 2nd file is 5 times bigger, but spent much more time than expected.

I know this can use “Delete Bookmarked Lines” feature for faster, but still hope EmEditor can be improved more.
Thanks.
