Requirements to run Websphere Client

I was wondering if anyone out there could suggest a configuration to run
Websphere Client.

I currently have a IBM laptop P4 1.6 GHZ machine with 768MB  right now and
it takes 20 seconds to rename a java field in the Visual Editor , 30 seconds
to start the Websphere Test Environment.  It is not speedy. (Perhaps I am to
used to native RPG programming and Visual Basic Programming?)

Our company is getting new laptops. People in our company are getting new
IBM laptop Centrino 1.7 GHZ machines with 1 GB of memory, so I had an
opportunity to test with a fresh one. I loaded up websphere and a couple of
our small apps and now it takes 12 seconds to rename a field and 21 seconds
to start Websphere test environment. 40% improvement.

We do java application, JSP, servlet programs testing in the Websphere test
environment.

I suggested that we instead see if we can get an IBM G40 which has a pentium
4 at 3.0 GHZ with max 1 GB memory possible  -or- see if an additional 1GB of
memory would help the Centrino based machine.

Is there anyone out there with a good PC configuration where there is little
waiting writing Java Apps and WebApps. Or is Websphere Client just slow!

I am looking for suggestions guys!

Thanks everyone
