com.apple.dt.Xcode.sourcecontrol.Git overloading CPU

Question

I'm noticing that Xcode is severely affecting my computer's performance. I can only have Xcode open for a few minutes at a time before everything I have open starts slowing down and my computer starts overheating. When I check Activity Monitor, there are usually 5-15 lines that say "com.apple.dt.Xcode.sourcecontrol.Git". Sometimes my app won't get past the landing page until I force quit them all. Has anyone come across this before? Are there any settings I can change to make this stop?

• Xcode version: 7.1.1
• OS version: 10.11.1
• Happens in Swift and ObjC
