I think it really depends on the language and project size. Any new project tends to make the IDE barely usable while it's indexing. Compared to, say, vi where everything is instant and there's no visual lag, I'd say it's slow. Even on 16 core CPU with 64GB of RAM and some IntelliJ JVM tuning, I still get some lag/stutter.
