Hi All,
I downloaded and ran the new v21a and did some timings on
several different machines and compared them to timings done
on v19 and v20...
I ran the timings on each version for 100 screen outputs at
100 iterations per screen output... for a total of 10000
iterations... and then averaged the iteration times... I
used the same exponent on all versions and machines... (an
exponent I am primality testing that is just shy of 11,400,000)
What I can up with was these results...
V19 V20 V21
----- ----- -----
PII at 266Mhz 0.579 0.578 0.586
Celeron 1 at 466Mhz 0.605 0.604 0.615
Celeron 2 at 550Mhz 0.289 0.288 0.223
P3 at 733Mhz 0.239 0.238 0.188
Athlon at 1333Mhz 0.100 0.098 0.077
Admittedly, while the 466Mhz Celeron 1 has almost double what
the iteration time was expected to be... (for some yet unknown
reason -- Prime95 is getting 98.9% of the CPU time)... the %
increase/decrease is still evident....
Note also that the Athlon *did* have a performance increase
on par with the Celeron 2 and P3 machines....
Eric
