<fixed>>   Here's a side by side comparison of the two systems.

I must say I'm a little bit disappointed ! The most I do on my system is to 
compile some stuff, and now it should be slower then at the moment it is on my 
systen ?!

Can someone explain me why all these tests are slower on a SA110 then on my 
ARM710 ?


The next question:

Why were floatingpoint operations in *all* kernels newer then #3854 only half 
as fast as in kernel #3854 ?

Here are the results for float with this kernel ?


#3854:

Arithmetic Test (type = float)              212.3 lps   (10 secs, 6 samples)

Arithmetic Test (type = double)             202.8 lps   (10 secs, 6 samples)


#4193:

Arithmetic Test (type = float)              106.9 lps   (10 secs, 6 samples)

Arithmetic Test (type = double)             109.9 lps   (10 secs, 6 samples)
