Yeah, Komodo (the editor and also the full IDE) and Eclipse are both slow. I haven't done a side-by-side comparison of the two to see which is slower though.
That said, the OP sounds new at this, and probably won't be pushing the limits of rapid text editing, so the speed should be ok for him.
If you want a full-featured IDE for Perl that's easy to use and has a lot of power IDE features (GUI debugger, code browser, regex helper tool, projects, snippets, macros, templates, and so on), then I think Komodo is a good compromise.
I don't want to sound like an advertisement for it though. I'd prefer the OP use completely free software tools. But at least ActiveState has been good for the community in general, and the editor component of Komodo is licensed under some sort of open source license.
