Hi,
Thanks for the confirmation.
My aim was not really to check compilers, but I just tried my small benchmark on 2.1.115 and the standard 2.0.35-2 RH kernel.
First, SMP on UP 386/387IRQ13 is working again... maybe because there is no more FPU instructions in the kernel ?
I have these general result: 115 UP : 24 min 30 s 115 SMP : 24 min 22 s RH 35-2 UP: 24 min 45 s
Is there a problem in my benchmark or the SMP kernel is no more slower than the UP one ?
Etienne.
