OK, I set it to NO and things did speed up quite a bit.

But there's a rub: The GUI client on Mac behaves as though the default
were NO. If you un-check the "Use memory-saving algorithm" checkbox,
then it should place the MEMORYEFFICIENTBACKUP NO option into the User
Preferences File. But it doesn't. You have to go edit the file by hand.

I agree that the default should be NO, especially with modern Macs that
have plenty of memory, and in that case the GUI would be working
correctly.

Thanks for the tip!
