You need to determine where the 'slow response' is - the robot control host or the Java GUI.
Test inventory from command line:
Check contents and compare:
vmcheckxxx -rt tld -rn <robot-number> -rh <robot-control-host>
Check and update:
vmupdate -rt tld -rn <robot-number> -rh <robot-control-host>
Commands are in ...volmgr/bin
What is the result?
Same or faster than Inventory through the GUI?
PLEASE always mention OS on the master server.
You have selected Windows 7 as OS - is this where Java Console is installed?
Where are you using the Java Console?
On the master server or robot control host?
On your desktop?
If using Java Console on your desktop, how are you logging onto the master server?
Using IP address or master server hostname?
If IP, add hosts entry on your desktop for the master server and then logon using hostname.
I have seen issues when logged onto master server as IP address.
