there are 2 other threads asking the same question ... on loading...
so you're apparently not alone with this issue.
saving the file should not take nearly as long. I notice that some saves will take about 4 seconds but that is only when I have something like Melodyne Editor in some tracks.... otherwise, the save is like half a second for a typical project.
Yeah... both actions should not take very long. read the other threads on loading to see what has already been discussed and offered as a possible solution to the long load times.
