Around the year 2000 when I was at another company, a Sun reseller set
up a Solaris server with Oracle for us.
At that time they tuned the system to be CPU bound.

This is a red herring, some resource is always going to restrain the
system, whether it's memory, disk, or CPU.
No restraint is better than any other.

On its own, I can understand that Fb may want to use as much CPU as it
has. However, in the light of relatively modest usage by mysql or
postgres (both averaging CPU load at 1.5-5% everyday), the argument does
not hold. Furthermore, shouldn't FB be more I/O intensive than CPU
intensive?
