 Kirkburn : It's something about the LinkSuggest. It didn’t start occuring until the new editor was introduced. Perhaps some code had to be re-written to get LinkSuggest to work with the new editor and that code change is generating the problem? And, it does not matter now which editor one is using: If it’s going to happen, it will happen … even on wikis that are using the old editor. When it happens, as soon as one types either of the opening brackets — either square or curly — the system slows to a snail’s pace, at a rate of about 1 character per second. As soon as one leaves the editor, performance goes back to normal.

As for me, I’m using Dell Latitude D820 Intel T2600 Centrino Duo @ 2.16GHz/2.16GHz and 2GB of RAM. (Thinking of getting a new AlienWare or Dell XPS laptop … still in navel gazing period, mind you).
