Today when our users try to log into SERP, upon launching we get the message "No Response from Network" for 6 seconds. Then the normal Login window asking for name and password appears.

After entering username and password we get the message "No Response from Network" for another 6 seconds before the Navigation Centre appears.

SERP also is performing poorly and is unstable with many resorts required.

Here is the Terminal output from the server :
