Slow TDE Exit Time

I notice that 3.5.13 takes a long time to exit. Normally I login from the command line and start X with the startx script. On my 2.3 GHz dual core system with 4GB of RAM and SATA II hard drives, TDE takes about 7 to 8 seconds to exit and more than once I have seen the system take up to 15 to 17 seconds to return to the command line. I do not have sessions enabled, logoff confirmation is disabled, I don't use eye candy, apps are already closed, etc. My virtual machine takes about 7 to 8 seconds to exit to the command line. On a 350 MHz PII system with 448 MB of RAM and ATA-2 IDE hard drives, exit time is about 16 seconds. I expect longer times but not that much. Yes, a PII is not a speed demon by any modern standard, and such a system pushes the envelope of "old hardware," but if TDE is targeted for older hardware then the long exit time is not a good marketing point, especially on a dual core system. The dual core system uses the proprietary Nvidia drivers. The PII uses the tdfx driver and a first generation AGP card. For the record, 3.5.10 never was a speed demon at exiting either. I just expect more from TDE. :) There is an enhancement request to provide an option to disable displaying the "Saving your settings" dialog box, but even if implemented, I doubt the dialog box is responsible for the long exit delay. What could be the cause? Is anybody else experiencing a long exit delay? Darrell
