The following may be somewhat off topic, but I have some problems with my new
P6NP5 motherboard from ASUS and a PPro-200 (256k). 
When I run the C-linpack or other floating point stuff I can't get
more than 14 MFLOPS (with double precision). With single precision
I get 69 MFLOPS which is fine. Is it notmal that the P6 has such a lousy
double precision performance?
What can the reason be?
The system has 64 MB EDO-RAM. And yes, all caches are enabled.
The C-linpack is compiled with cc from -current (version 2.7.2.1).
pgcc doesn't help.
The C-linpack doesn't use any special library routine except the floor
function.

It would be nice if someone with a P6-200 could send me some results
of FP benchmarks.

BTW, Dhrystone 2.1 delivers 432000 dhrystones/second. Is this ok?

TIA for your help.
