I have found that the cost of printing the spew often slows down compiles measurably, especially when spewing to an xterm running on a local XFree86 process. Even with syscons, this is noticeable. I generally tend to run my builds behind the screen port these days, which helps (screen implements a virtual display buffer that disconnects screen updates from the display client and the slave pty). Another optimization worth noting is running make -q, which silences a lot of that spam (urban legend has it that the synchronization in parallel makes to write the build messages causes noticeable amounts of contention).
