Re: Lawson 8 and Performance

Welcome to the wonderful world of Lawson 8! There are many, many
changes in Lawson 8 that make everything run slower. I am by no means
an expert and we are still in the process of doing the upgrade, but I
at least can give you some insight to how Lawson works. I am not sure
how much you know about Lawson 8 and how it works, but if you contact
me offline I can give you my phone # and I can give you some tips. One
thing to look at is Lawson's performance guide. Check out the
knowledge base article # 128978. This is a continually updated article
on how to increase the performance of Lawson.
