I'm having the same problem with cakewalk. Until recentely I used Sonar, but then switched to CbB. Sonar wasn't particularly fast at start up but it wasn't nearly as slow as CbB is. I'm running it on a 500 gb SSD drive, Windows 10, i7 processor (bought in 2014, but still a pretty fast, as I can open all other programs super fast. I had the same amount of plug ins I had with my prior configuration with Sonar, or less. I really don't know what to do...
