This morning I tried compiling up an up-to-date kernel, booting it, and then starting a make world. I stopped it after I noticed that the disk was getting an incredible pounding during C compilations that previously would be almost totally CPU-bound. My impression from "systat -vmstat" was that somehow the effectiveness of the namei cache had gotten drastically reduced, and the lookups of the names of include files were causing a lot of disk activity.

Has anyone else seen this?
