Frank,
Your earlier reply did not make it through.
This is kinda what I thought would be the case, even though I was hoping for better. It seems that the way to go is to use another compiled language for the number crunching and Rev for the UI. This is doable in my case because I write out all the intermediate files as .csv arrays. I have no experience with which compiled languages might be easy to read in the array from a file, do a bunch of math, and then write out a new array that Rev an read in and display. Time to start looking.

I'm not seeing it on the list. Transcript is actually faster than what I was able to come up with for PostgreSQL -- much faster, in fact.
Ada is WAY faster than either one of them -- a fraction of a second for this test.

Read the earlier versions of this thread for the fast methods. This example is just for a specific test between Transcript and PostgreSQL

Frank,
This is a simplified algorithm that I think would best translate directly between Transcript and PostgreSQL for a time trial. Just make sure the PostgreSQL code is an item by item algorithm also.
Thanks, Dennis
Transcript output on my machine: 1,000,000 Element Sum = 500500000 Elapsed Time = 11.467659 seconds.

Hi again with a little addition,
The initialization of the test array takes about 36 seconds. Following version does the same in much shorter time:
on mouseUp
put the long seconds into zap
--if number of lines of the keys of gTestArray is not 1000000 then --already done the init
put empty into gTestArray --start with an empty a variable
repeat with i = 1 to 1000
put i&comma after x
end repeat
repeat 1000
put x after gTestArray
end repeat
split gTestArray by comma
put the long seconds - zap
--end if
put the long seconds into st
Method6
get the long seconds
put " Elapsed Time ="&&(it - st)&&"seconds." after msg
end mouseUp
In this case the initialization takes about 10 seconds on the slowbook
