Simon, Did you change anything on your network recently? Are you doing auto negotiation on the Ethernet ports on the Netapp? If so, force them and the switch port to 100Mbit full duplex (unless you are using Gigabit Ethernet which you will leave as Auto negotiate). Run "ifstat -a" on the Netapp and see if you have excessive errors/collisions on a interface. Run tracert from the machines having slow access to the Netapp and see if they are going through any unusual hops. Mike

Hi,
I have sen over the last few days a marked decrease in CIFS performance from our 760. We have a shell for the PC (TCSH) and if I perform an ls -l on a top level share mapped to a network drive on the PC I get a 30-40 second delay before the list is returned.
I saw several lsa lookup errors last week, but at the moment these are all clear - but still the performance is poor. We use UNIX style qtrees, and have both WINS and NIS services.
Any ideas?
Simon
