We actually disclosed all the internal results on the testing to date with zSeries. It is available on our Website in response to the recent articles off linuxworld.com.
It is a tremendous effort I can tell you to do Benchmarking with large mail (millions of users) environments, all the so called products/parts, IMAP/POP, MTA, LDAP, Filesystems, Storage, Blasting tools, reporting tools, on and on. I can say that thanks to the SuSE and IBM engineers we have come a long way with Linux results on zSeries. We have made every effort to not be "on the bench with a tone signal" using real profiles, how many users, checking this or that, size of message, time during the day to check/send you name it. Thanks again to Hans Reiser, Chris Mason, Bernd, Hubert Mantel, Andrea Arcangeli, and the 1/2 dozen members of the IBM Engineering team for the work.
