EXR workflow

I'm trying to setup an openEXR workflow, but I just get 20 fps out of DaVinci... I tried all types of compression with no luck.
I'm using an 8 core mac with an Caldigit RAID (600MB/s), 3 Quadro 4000 and an GT120.

Which year is your mac pro from? What frame size are your images? I've been fairly impressed with EXR performance in Resolve.

Unlike DPX, EXR files are not designed for efficient disk I/O. There were designed for VFX images where disk speed of a few frames per second was considerably faster than the VFX render speeds. We continue to find ways around the file format limitations to improve I/O for EXR but in the meantime, depending on your workflow, consider the 16 bit floating point dpx files Resolve reads and writes.
