Hello. You can add me to the list of folks having similar trouble. Patches take 30-45 seconds to load. Using latest plugin, 2.5.1 AU under digital performer 8.07 on a Macbook Pro with OS X 10.10.3. Other than the lag on loading patches, plugin works fine once a patch is loaded, though the interface seems a bit sluggish when toying with parameters while the project is playing.
Best,
Chuck
