Booth When you say "Users who are used to Powerpoint", Are you refering the PC application that takes 20-40 seconds to come up(on a good day) on my PC at work? And are you being held to THOSE kind of response time standards on the AS/400? (By the way, ask your user to write Monthend Manufacturing Close out in Powerpnt or Excel) Where are we getting a bad response time? On a interactive program which should only do 20-30(tops) I/O's per enter key? Or are you doing 100-1000 I/O's per enter key where you'd notice the hit? If so WHY are you doing that many even now? Or is it a Batch job that may run 10,20,30 minutes longer? Is this on a CISC machine? Will that performance be more than made up when you eventually move to a RISC box? Will you still be using the same files with date types when the new RISC box is superceded by an even faster processer in 98-99 time frame? Would you notice it even less then? Just curious? I mean I want fast response like the next guy, Thats why I only do 20-30 I/O's per enter key, Watch what records I'm locking and why. I don't leave a record locked on a screen while the user makes up their mind. I watch my Data Base Seizes. I streamline my Batch programs(buffer them, Do selection in OPNQRYF, Share Indexes, etc. Accumulate update totals in an array then update the record - [neat trick, I dropped one batch process down from 5000 Update I/O's to 20 using that technique]) (I even used to do a 1 hour session on "Programming for Performance" in which I showed how to improve on alot of these conditions.) I do all those neat Performance things so that I can take (for a short time frame maybe) a performance hit on strategically important things like date and time types.
