Linpack
The Arm has been tested using the linpack benchmark from [1], built with gcc with -O3 (Optimisation level 3). Run with array size 200.
With software floating point
Memory required: 315K.
LINPACK benchmark, Double precision.
Machine precision: 15 digits.
Array size 200 X 200.
Average rolled and unrolled performance:
Reps Time(s) DGEFA DGESL OVERHEAD KFLOPS

Hardware floating point (-mfloat-abi=softfp)
Memory required: 315K.
LINPACK benchmark, Double precision.
Machine precision: 15 digits.
Array size 200 X 200.

Whetstone/Dhrystone
Code for these tests can be found here http://www.rowley.co.uk/arm/whet_dhry.zip.
All code compiled with gcc options -float-abi=softfp -O3
Whetstone
Loops: 1000, Iterations: 10, Duration: 24 sec. C Converted Double Precision Whetstones: 41.7 MIPS
Dhrystone
Microseconds for one run through Dhrystone: 1.2 Dhrystones per Second: 809061.5
Rebuilding the Whetstone test code with 'gcc -mfpu -float-abi=softfp' gives better results:
Loops: 1000, Iterations: 100, Duration: 106 sec. C Converted Double Precision Whetstones: 94.3 MIPS
However, the majority of compute time is spent in the SQRT function, which for the above test was built without -mfpu=vfp. Using a library with vfp give the following much improved result :
Loops: 1000, Iterations: 100, Duration: 15 sec. C Converted Double Precision Whetstones: 666.7 MIPS
