How to reduce abnormal CPU usage.

I've been using Live for years, and I know (or think I know) all the tricks for reducing CPU usage. But I've run into a problem recently that I can't figure out.

When idle, Live routinely displays 20% in the CPU meter after loading a song (and buffering), and then bumps up to 70-80% while playing 5 or so audio clips. When I create a new set, the CPU meter is low, but holding down a chord on Operator creates a CPU spike to 20-30%. 

I erased my hard drive and reinstalled OS X (El Capitan) a few weeks ago, so any OS indexing should be finished by now.

No other programs are running, and WiFi and Bluetooth is disabled. kernel_task is running at normal CPU levels. My buffer is maxed out. I have an Intel i7 chip and 16GB of RAM, and a 1TB SSD that's only 20% full. Pretty baffled at this point! Any ideas would be much appreciated.

    I'm having the same issue. I've been using Live for years. Runs well on my older iMac, but my new powerbook (more powerful than my iMac) is consistantly suffering from cpu spiking over 100%. It's basically unusable. The laptop was purchased specifically for using Ableton in live settings, so yeah, any help would be great.
