>Although I am starting to question the value of VIO... As well you should. As a performance/capacity analyst for over 27 years, I used to recommend VIO for small datasets (small has increased over that period), but now I don't think it's worth it, any more.
DASD is so fast, cache and channels are fast and we can do in memory buffering, so VIO is (mostly) a thing of the past. Especially for overhead-fetishists, since the CPU to do VIO is higher than that to do real I/O. - Too busy driving to stop for gas! ---------------------------------------------------------------------- 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
