Yes, true, you can construct a machine on which any project you care to run is CPU bound.
You can also construct a machine on which any project you care to run is I/O bound. Which kind of makes your comment "kernel compile is not CPU bound" kind of pointless, no?
That being said, I just downloaded kernel source on my old laptop just to do a sanity check, and it's pinning all 4 of my cores to 100%, so I don't know that to tell you. Perhaps your beefy server (with, I assume, a powerful CPU) is not a typical scenario.
