I thought I had it at my desk, but I can't find it now....] had a long detailed series of articles on the 320, one of which said they really sucked air doing serious multi-user work. I copied the articles and gave them to my IBM salesman, who's looking into possible answers/rebuttals. It was unclear from the article whether the problem was inherent architecture, cache size (which would be somewhat remedied by larger cache on xy0, y >= 3), or AIX (which could at some point be fixed). It's necessary to note that _Personal Workstation_ could better be named _PC Hotrods_, and they may have some editorial bias in favor of not giving their Everex 486-using readers bad cases of RS/6000-envy. But the numbers they published were disturbing. This may all have been discussed before I discovered that this newsgroup was where the RS/6000 stuff got posted. If so, I apologize for bringing it up again....
