Low performance in EditControl

[Michal]

I'm experiencing very low performance when using Syntax Editor. It doesn't matter how large is the source string (I didn't try with files).

I observed it with following setup:

- HTML language

- Outlining enabled

- Intellisense disabled

When I select text or type something in the control, CPU usage is vastly increased. If I continuously select back and forth, the CPU usage can jump up to even 50%. This effect is reduced if I don't specify language, but even then there's a noticeable lag.

Can I do something about this?
