GPU performance question

Hi. We've got the current version of openmm with CUDA10 on a machine with an rtx2080 GPU. The DHFR benchmark with explicit solvent, PME electrostatics and 2 fs time step estimates 444 ns/day. For our first run with a real system, we have a protein in explicit solvent, 79,000 atoms, octahedral box an...
