And I thought long names exist to support C++ with its quasi-Hungarian notation for function names.
It's not linear. Increasing BLKSIZE by a factor of ten will not yield a tenfold performance improvement. And increasing BUFNO by a factor of ten will not yield a tenfold performance improvement. Don't know about striped RAID. I suspect there's no software support for the desirable parallel I/O. -- gil ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
