Why is "make test" so slow?

Why is "make test" so durn slow?  Our tools run individually seem pretty
snappy on my low-end box (P200/64MB) but running "make test"  is like
watching paint dry.  I'm seeing something like 1 test per second!

Please feel free to point me to TFM if this question is answered there.
