Long spaces between render times even with 3 second renders

[jessebafia]

While rendering out my animation my frames are getting finished with the actual render in about 3 seconds, which is obviously great. What is not so great is the time between frames.

After it is done rendering it says "frame finished" in the bottom left for another 15-45 seconds then saves the frame for another 4-5. Why is there that 15-45 second time where it's just sitting there and is there anyway to correct this? I'm unable to share any screenshots due to the NDA.

Any suggestions to fix this definitely appreciated!

Check Console window for render logs and compare with Live Viewer sessions. Be aware of triangle/hair counts will be different between Live Viewer vs Picture Viewer. And triangle evolution takes time. How much triangles so much render times. Lower that if it's reason.
