I know it's an Omnimover but I'm pretty sure it has a relatively low capacity because the ride vehicles only seat two people. I'm almost positive I've read that it's less than 1000 per hour, but who knows. It must be lower capacity than other Omnimovers with larger ride vehicles. I believe I've read the two track version of TSM had higher hourly capacity than Buzz, but again who knows if that's accurate.
Looking at Touring Plans reported wait times for the past few days, the wait is similar to Winnie the Pooh, sometimes 5-10 minutes less. The Buzz wait was typically around 30-40 minutes.
