It was from time I was trying to stress whopr to get issues like this one soon. It does not matter if we build application in 1/100th of second or 1/200th of second and too much parallelizm could slow down build of many small binaries. I guess we could shoot for resonable user response. UI guys thinks it is about 1/3rd of second, so I would not mind tuning number up until compilation on not terribly high end system approximately gets to this time. I don't think this is however terribly related to large unit sizes and inliner stuff. Honza
