You don't mention what version of System V your friend is running on the 3B2. Is it 1.0, 1.0.1, SVR2v1, SVR2v2, or SVR2.1 (or something I never heard of)? What Cobol is being used? Does it compile to pseudo-code that is then interpreted by a "runcobol" command? Does it do a lot of floating point arithmetic? We all know that the 3B2/300 has rather marginal floating point emulated in software. You don't even mention what configuration 3B2 you are talking about. Is it a 3B2/400 with math co-processor (MAU)? Without these details, it's really hard to come up with any solution, but (assuming you are talking about SVR2v1 or later) you should look in the System Administrator's Guide under performance and system tuning to find out what the tunable parameters do and how to adjust them. Are you using one or two hard disks? If two, put /usr on the second drive. More details get better answers. Good luck. -- Ron Heiby heiby@cuae2.UUCP (via ihnp4) AT&T-IS, /app/eng, Lisle, IL (312) 810-6109
