RAC WINDOWS PROBLEMS CONFOUND -64 bit

2 node dell poweredge 59nn with md3000 das storage - 64 bit windows,cisco
switch for interconnect, UDP 1GB
storage raid 5 on das with 7 disks
semi spatial application for land management
widows .NET Application using IIS as web server - PL/SQL calls to D/B THRU
10.1 CLIENT
Database 10.2.0.1

I sent a post earlier about 32-bit windows ,how when both nodes ran
performance was poor, stop a node and performance is good.Well i have
upgraded
to 64-Bit and the same things happens. When I run a j2ee application against
same database it performs well. I have fixed hosts files and tried changing
the datasource on the client to point directly at an instance and also via
the load balancer Tns names entry. So far all attempts failed.

I know that the application source code is poor, but when it runs on one
node it is fine , and that is the vendor response.It is hard to argue
against. Tomorrow I will start a thorough analysis, but any heads up will be
appreciated.
