Thanks - I have managed to nail my "problem" down to one subroutine - having optimised this routine I have halved the processing time for this program.

You're forced to use 'best practices' to optimize a program - but if you compile a routine with UniData's Profiler Option 'on', the really interesting thing is that you can see where the system is spending a lot of time, or doing a lot of recursion - you can see clock time spent, CPU time spent, and number of times the subroutine was called. I found it immensely useful to find areas of programs I could optimize further to get the most 'bang for my buck' - it also led me to find a subroutine I called many times that had a file open within it - by fixing that one issue, I saved 30% on one routine...

RE: UNCLASSIFIED RE: Unidata "Flashbasic"
Ah yes, RAID :-( Unfortunately you have to get the program into BEBUG state before you can start the process of profiling, then enter a "$" or "#" at the ever-popular user-friendly "::" prompt, then "C", then when the program executes a "STOP" it goes back to "::" again and you have to enter "C" again to get back to TCL. At least 3 user interactions and the user has to have TCL access by the look of it (I haven't tested that). And you couldn't do it at all in a PHANTOM. Whereas for the UD model, to get coarse-level timings, you just change your menu program (or your UniObjects host?) to add a "-G" to the "RUN ..." statements it emits, or even put one in the LOGIN Paragraph. 'Look Ma, no hands!', the user doesn't even have to be aware of what's going on, and you can profile a PHANTOM job. I have found very-low-level profiling useful in a development or test environment, but often only after coarse-level profiling in Production has identified which little beastie is soaking up all the CPU!

RE: Unidata "Flashbasic"
It was easier to document than I thought... 1) Decide what program(s) to 'profile': You would probably only profile the header program FIRST, then see what called subroutines are taking a while in total, then switch your profiling to THAT subroutine only. The profiler generates A LOT of data, so you don't want to profile all 35,000,000 lines of code you've written in a single sitting! 2) Compile the programs you want to target with a -G option BASIC BP PROGTOTEST -G 3) Run the program using the -G option. RUN BP PROGTOTEST -G Note: If your PROGTOTEST is an embedded subroutine, no problem, you would type RUN BP MASTERPROG -G , and the -G option would start profiling on the MASTERPROG in 'summary', but would do 'detail' profiling on the program PROGTOTEST as you compiled it with the -G option. 4) Shell to the account you are working in and find files marked 'profile.NNN' and 'profile.elapse.NNN', where NNN = PID. These are NT or *nix files - not VOC entries. So you can't see them until you go to to OS level for the account you are in. The profile.NNN shows the time in actual CPU usage... It shows %time of time spent in the listed routine, cumulative time in secs(*more on this in a moment), seconds spent on this routine, calls to this routine, routine name The profile.elapse.NNN shows the time on the CLOCK, so if you had to key data in to a subroutine, you can expect to see it near the top of the % of time occupied. %time spent in the listed routine, cumulative seconds spent to date on the funtions (*more on this in a moment), Raw Seconds spent, # calls to this routine, routine name. The Cumulative time is not sequential: You may see data like this: %time CumSec Seconds Calls Name 10.03.00 3.00 1d:\account\_ROUTINEC 10.06.00 3.00 1d:\account\_ROUTINEA 6.78.00 2.00 1d:\account\_ROUTINEB See - the CumSecs is not the time elapsed for the ORDER the routines processed in, but the Cumulative time for the routines in the order of %time spent. Also - if you have not compiled a routine with a -G option, the WHOLE ROUTINE shows up on one line, as shown above. However, if you had keyed ROUTINEC with a -G option, you would see this instead: %time CumSec Seconds Calls Name 10.03.00 3.00 1d:\account\_ROUTINEA 6.75.00 2.00 1d:\account\_ROUTINEB 5.06.50 1.50 6d:\account\_ROUTINEC:1000 2.57.25 .75 1d:\account\_ROUTINEC:10 2.58.00 .75 1d:\account\_ROUTINEC:100 Where the # after the colon is the internal subroutine label being exectuted. In this case, I can see subroutine 1000 is called 6 times in the program, so that works out to be .25 seconds a use. Not much to fix there compared to 10 and 100 at .75 each, UNLESS I didn't know subroutine 1000 was being called 6 times! As I said, you can find out SO much about your code running this - you may realize that optimizing one or two sections of a program will have a large impact. As well, once you get a printout of what programs are using what amount of time, it will lead you to do a -G on them - in the example above, I can see I should also profile ROUTINEA to see if I can hammer out some time from the routine. Once you are done with profiling, you should recompile the program WITHOUT the -G option - this will produce the smaller object code again since it will be built without the 'profile' handles. Hope that helps someone!
