There is no doubt that AOE is a performance hog, but it does run OK on our
system (620 / 2179 w/ 1GB RAM) which is lightly loaded.  We do need many of
the features provided by AOE, so for us it is the only alternative.  We've
noticed it takes a long time (5+ seconds) to load an large order (25+ lines)
for amendment, but haven't had complaints about initial entry of a large
order.  It reprices each line every time you amend an order.  It also checks
for credit issues that might cause an order to be suspended.  IMO, it would
take a lot of resources to "improve" AOE to make it faster and you would be
better off buying more hardware.  It is a huge, complicated suite of program
that doesn't use many shared routines.  Angus, it would be interesting to
hear your machine configuration, typical number of active users, size of
orders with problems and the response time you are experiencing.

Angus:

Try the performance adjustment.  Generally, it's pretty good.

Does order entry run acceptably for small orders?  Define 'many lines'...
10? 100? 1000?

You need to do a couple things to figure out where your performance problems
are coming from.  Does the software do any SQL or OPNQRYF?  Watch the jobs
as they run.  Do you see very high CPU but little I/O?  High CPU and low I/O
reeks of logical file problems - you're either building them (SQL or
OPNQRYF), or rebuilding them (LF with the REBLD option turned on).  Or, are
you seeing record locks?  In this case, you'll see LCKW on WRKACTJOB.

One way to speed things up is to get rid of old data.  You might have files
that simply need to be reorganized, or you might see significant performance
improvement by purging and archiving data.  Check out
http://www.arctools.com .  ARCTOOLS is a disk optimization utility that can
help you reorganize the files you've got, and it will also help you purge
and/or archive your data.  If you have an existing purge-only routine, it
will add the archiving feature without programming.  If you don't have a
purge routine for a particular file, it can purge and archive data without
programming and without locking files.

Good luck.

Hi

We have terrible problems with the speed of entering orders using advanced
order entry because we have many orders and many lines on each order. We
have just upgraded our memory to 896Mb to try and alleviate this, and have
been recommended to leave the performance adjuster on at all times. Does
anyone else have similar problems? How do you set your pool sizes?

Angus
