The advantage of multilanguage programming cannot be dismissed. The
ability to get at BLAS is essential if speed is required. I have done a
few tests on the SP2 using GNAT3.11 (options -gnatp -O3)

	Level 1	(daxpy)	Ada 17Mflops	ESSL	60
	Level 2  (gemv)	Ada 12Mflops	ESSL	140

I have not done level 3 at the moment.

There is a binding to LAPACK on the gnat distribution site.
