I have had a lot of problems with large replace functions and know there has to be a better way. For example I have a replace that is replacing all spaces in a 100K line text file with nothing. It is taking over 10 minutes and eating up 100s of MB of memory. The file is only 1.7MB. The same operation takes about 5 seconds in BBEdit. There are about 600,000 replacements done in the process.
Replace Operation terribly slow compared to other editors

In general, the Replace panels performance is fine. It appears you’ve found a pathological corner case.

It performs fine when it’s not doing that much work. On any medium to large job it is always orders of magnitude slower than BBEdit.
