We are running a Windows 2003 Standard server as a vm using VMware ESXi. This server is running service for unix 3.5. We have 2 NFS shares setup on the Windows server which exports to 2 other Unix servers. The VM is setup using 4GBs of ram and 4 processor running at 2.4Ghz a piece. We are noticing high CPU utiliaztion with the rpcxdr.sys driver which is used primarliy for SFU. CPU will spike to over 90% and users notice slowness accessing server. Is there anything I can do to decrease the overhead used by SFU and is there any known problems using SFU with VMWare ESXi? Any ideas would be very helpful. Thanks
