System extremely slow and got kicked out while waiting for response! ouch...

System has been slow during the entire weekend and is slow again this morning(yesterday).  It takes forever to connect, to save and to publish.  It is not a problem with my connection.  It is frustrating because the system logsoff automatically after a few minutes of idling.  The least that you could do to alleviate the problem is to extend the period of inactivity before logging us out.  You see, because the system is slow, I normally switch screen to do something else in the mean time.  When I return and I see that I have been logged off it drives me nut because I need another 5 minutes just to log in.  Moreover, the logging process requires many iinterventions so I cannot click to login and let it loging by itself.  You know what I mean.  Anyway, it would be so much nicer if you could at least extend the idling period to at least 30 minutes before logging out.  Thanks
