Re: What About Price vs. Performance?

I think the 3-1 ration was a mistake, Jon.  I think the correct ratio was
30-1.  On a 460 CPW machine, it shouldn't be taking 25msec to read 20
records from a file, build a subfile, then display the result on a 5250
device.  For example, it takes my 300 Mhz Celeron PC only 4msec to read 51
records from a database table and copy them to another table.

If I correctly follow Joe Pluta's later comments, his earlier 5250 estimate
was too high.

reduce the statistical error, but a 3-1 ratio isn't bad.

Actually it is a lot better than not bad.  Consider that (if my pricing
info is correct) that on most AS/400s a Batch CPU second is about a 6th to
a 10th of the cost of an interactive CPU seconds and you have the Web
application significantly outperforming the 5250.

Also we need to remember that CPU usage doesn't matter a hell of a lot
unless we're already using all we've got.  Most systems I've seen are not
constrained by CPU utilization.
