You should easily be able to get 300 HEADs per second on just about any

Take a look at this, for example:

That benchmarks a Hello World example written in various ways, including
static html, so that is slightly more data than just a HEAD request.

Not that these are very accurate, but they at least show you that Apache
can easily do a lot more than 50-100 HEAD requests per second.  You are
doing something very wrong.
