Subject: Slow processing with g77 in egcs

Hi all,

I installed egcs-1.0 in a PC164-LX having a cpu 21164a (600 MHz) cache=4
MB ans RAM=512 MB.


I teste the machine with a f77 code that ran in several platforms.
For comparison this code was ran in a axp 255. and a PC164 LX with a cpu
500 MHz, running DU a DEC fortran. Results:

code in PC164LX with cpu 500 MHz was 7 times faster that in the axp255.
code in the PC164LX with cpu 600 MHz running linux and egcs is only 2.5
times faster than axp255.

So my question is: Whyt this difference? shouldn't the code be faster in
the 600 MHz? 

I tryed all the flags tu make the code faster in the PC164LX with cpu 600
MHz.

I would appreciate any suggestions.

regards,

miguel
