That seems a little low - can you try with the Athlon32 build as well as the P4 build?

Oh well! Looks like clock for clock, Athlon64 is equivalent to Athlon32 for sr5sieve

The Athlon-64 speed could probably be improved by writing a suitable 64 bit mulmod in assembler and finding the right GCC options to compile it as a native 64 bit application. I don't have access to one of these machines myself, but if someone running 64 bit Linux on one wants to have a go at this I will help.

p=55e9, 324 candidates.
Srsieve 0.3.4 compiled with 'make ARCH=i686 CC="gcc -V4.1"':
Column A with 'ASSEMBLER=yes', column B with 'ASSEMBLER=no'.
Column C is sieving one candidate at a time with NewPGen 2.82.

Code:
                                   A      B      C
Machine                    MHz   p/sec  p/sec  p/sec
------------------------  -----  -----  -----  -----
P2/400 (Deschutes)          401   3470   2920     44
P3/450 (Katmai)             448   3890   3250     50
P3/600 (Coppermine)         601   5880   4740     70
P4/2.4 (Celeron 128K L2)   2880  11190  10960    100
P4/2.4 (Northwood C)       2912  12520  12200    154
 -- two instances hyperthreaded  19890  18600    236
It seems the assembler routines hardly benefit the P4 at all.
