I thought that TStringList is slower than a simple string. Anyway, I can't use "Richedit.text = stringlist.text" because my text must be formatted (colorful). This is why I decided to write a HTML. Now I use FastMM and I can write long strings. But Delphi started to behave strangely since I use FastMM and I must read all its documentation :(
