RE: WAS Express 6 vs. WAS Express 5.1 -- WEB400

You need to have at least 1 gig of memory in the ASP that WAS runs in
for it to perform okay for a small number of simple apps. This usually
means a box with 2 gig of memory on it. Java performs poorly on partial
processors as well so if you have a partial processor for the partition,
that may be part of your problem. Also, if you have the system
automatically move memory and it takes away from the ASP WAS runs in, it
will cause WAS to run slowly until garbage collection runs.

IBM has some documentation on performance tuning. If you have a support
contract, you may want to give them a call. Some of this is probably
also in their knowledge base but not everything is.

Actually Matt, I didn't state that very well. I am currently using WAS 
Express 5.1and am trying to decide if I should try the jump to 6. I run
my 
web stuff on a logical partition. The core RPG guys here have yet to
give 
up too much memory to my partition so it does not perform quite as well
as 
I would like. If 6 might speed some things up I might have to try it. I 
understand that if I were to have them both up and running it would
bring 
things to an even slower speed, but initially I might do that just to
take 
a look at 6. I am correct in thinking that they can both co-exist right?

WSDC 6 brought this on. I have installed it and am much happier with the

performance on my PC, so this got me thinking about moving the server 
itself to 6.

Thanks for your unput!!

WAS Express 6 has all the features of the base version. WAS Express 5.1
doesn't support EJB's and a few other things that the base version does.
WAS performance typically gets better with each release and since
there's typically migration work between releases, I can't think of a
reason to start with 5.1.

WAS 6 does not install with RSTLICPGM. Take a look at
http://www.itjungle.com/fhg/fhg120705-story02.html for installation
instructions.

Make sure that you order the latest group PTF for which ever version you
decide to use and apply it before you try to start it for the first
time.

Anyone have any input, or any sites with side by side comparison of the 
two?
I am thinking about taking WAS Express 6 for a spin but don't know if 
there are advantages to it or not and I am having trouble finding 
anything.
