True, but speed isn't something a text editor really has to worry too much about, as long as it's fast enough not to be irritating.

1. This isn't true for complex text editors.

2. Java isn't slow if that's what you were insinuating. According to the shootout game the java vm is generally faster than mono.

Interactive response is not measured with a number crunching benchmark. It's measured by UI latency. Eclipse itself (assuming SWT is considered better than Swing) is still remarkably slow when compared to MonoDevelop.

I see you haven't used Nedit.
