LPD Session Delays
The LPD session delay exceeds the critical value set in Expert Thresholds. The "session delay" metric combines network latency (i.e., the time spent waiting for data to traverse the network) and application processing time (i.e., the time spent waiting for the server or application to respond to a request). Application Response Time for NFS is tracked with a separate Expert Threshold.
If the Expert Threshold for application processing time is also being exceeded, the slowdown is probably the result of a problem with the printer or the application trying to send it data.
If application processing time is within reasonable limits, network latency must account for the bulk of the session delay. You should look for problems with the network. Do you have enough bandwidth between the application server and the clients that use it? Are the routers between the systems configured correctly?
