Really, interesting. What release?
One of our guys tested SuSE 9.1 running a Progress database and Fathom Replication on a pSeries 530 to a second pSeries 530. I can't say what the exact results of the testing was, since it wasn't my project, but I know that we were disappointed in what we found. We do use SuSE 9.1 (and now 9.2) for specific imaging apps in our organization.
