Just from the user's point of view:
KDevelop is essentially unusable when I'm compiling my project (9 parallel
make jobs). It seems that the outputview just cannot handle it quickly enough.

It's a typical cmake/Qt project compiled with make -j9, the full compilation
takes about 30 seconds and produces ~500KB output (~2300 lines).

If I set make jobs to 1 or CMAKE_VERBOSE_MAKEFILE to off, it's all fine.

I'd be grateful if you added this as a test case. Compiling, say, KDevelop
with the same settings should give you the same drop in performance.
