Titolo: Benchmark e confronti

PEr curiosità ho effettuato un test di prestazioni (benchmark) alla mia
macchina Linux (con mandrake 10.1 con kernel 2.6.8.1-12mdkcustom con
opzione preemptive attiva che gira su un AMD Athlon64 3000+ linux è a
32bit, poi lo testero quando vorro su un OS a 64bit) ed ho ottenuto dei
risultati, solamente con cosa li metto a confronto, cioè dei dati di test a
se stanti valgono 0, dove posso trovare siti che riportano dati di test per
fare le comparazioni...
Come programma per fare il test ho usato unix bench 4.0.1, casomai conoscete
altri tool più usati ditemelo.
I dati ottenuti sono:

Scusate se insisto ancora...
Online ho trovato un altro tool per fare i test chiamato "Byte Unix Bench"
molto simile a quello precedente ma che una volta eseguito da volori di
molto differenti, adesso vorrei sapere, qual'è il più autorevole?
Sul sito del tool cè un solo benchmark attuale (cioè su macchine di nuova
generazione, altrimenti c'è u nutrito insieme di test sul 486, e parenti)
di un doppio xeon 2.4 ma mi sembra pochino per fare comparazioni.
Chi mi dice un sito contenente più test, oppure mi inviate i vostri (se
volete)...

PS: 
Allego i risultati attuali..
La macchina è la stessa di prima...
