In WikiEditor when i have to replace a lot of items (over 100), replace is slow.
But when i have to replace 300 and more items (words/sintaxis) in a small page with about 18,000 bytes, replacing proccess in Firefox hangs my browser for few seconds/in Chrome hangs only tab, until replace is done; and at that moment CPU is loading to 100%.
Atfer replacing is done everythink return to normality.
Also when i have to replase only several items (less than 100; tens) in an (big) article with over 100,000 bytes, replacind proccess also is slow
I must mention that, when i do the same thing in Notepad++, it replace all items (thousands of letters in thousands of text rows) in less than 1 sec.
