Zix (zixh) added a comment to T64894: Cycles slow CPU render when using CPU + GPU with GCC 8.3 build.

I was also using a custom build, and the official beta build does not have this issue. I will test downgrading GCC and seeing if that helps.

I was having a similar issue with some of my own files and was going to file a bug. Testing my setup with the blend file posted in this report, I also have this issue when using GPU+CPU rendering. Disabling the Suzanne head from rendering produces an almost-instant render. Leaving it enabled and with its subsurf modifier shoots the render time to more than 2 minutes (2:16.49 on my last render), with the major hang being tiles rendering on the CPU.
