>I wonder about teD's statement that there remains a performance edge for VIO.
There's always a caveat! I haven't had a paging system for over 15 years. On memory-rich systems, VIO (or any DIV solution) beats physical I/O (even to cache). If you're paging, VIO isn't worth it! If you're not, go for it. - -teD I’m an enthusiastic proselytiser of the universal panacea I believe in! ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
