This is still a problem in 2017 and your fix made my day ! Using Cubase Pro 9 and NI Massive was the slowest loading synth in my DAW, around 6-8 seconds....now it is 0.5 seconds ! THANK YOU !!
How to do it:
1. Open Massive in stand-alone mode
2. Click Options
3. Click the Browser tab
4. Set "Database hit-count display" to "none" !
