Hi Ivan,
There are no formal recommendations that I can point to beyond the hardware requirements stated in the install guide, but what I can say is that based on my experience the vast majority of time spent during SCA deployment is in compiling JSPs (which is actually part of application startup). You can get an idea of how much time is spent on your system by taking the difference between the oldest and newest file timestamps from JSPs in the
usr\sap\LKG\J00\j2ee\cluster\apps\sap.com\me~ear\servlet_jsp\manufacturing\work
directory immediately following deployment (substitute your own SID and instance number in the path).
Usually AV recommendations are under the juristiction of your company's security policy, so we cannot make any recommendation here. All I would say is that if it does not violate your company's policy then I would exclude the \usr, \sapdb, and Oracle or Sql Server installation directories. It's difficult to say how much of a gain you would get for deployment though.
As for NetWeaver, you should be able to run with the default configuration (e.g. that which comes with the Developer Workplace install). I don't know of anything that you would adjust from the default value that would help speed deployment.
On the database side I have always run Oracle enterprise with the default configuration. I have never seen any bottleneck here granted there's adequate physical memory available.
If you find JSP compiling is the biggest offender, then you may want to log a ticket against ME. There was a work around done in 6.0 that may we may be able to backport to 5.2. No guarantees, but it's worth a try.
