your result is perfectly fine.
in most case (depending on the scene) load is going to be between 70 & 90%. In order to maximize that, You need fast CPU (for instance I run flat 4Ghz on 6core) & turned out C states. Once Your CPU clock stays optop, it reacts faster to those "calls" from GPU to send information.
Another thing is GPU frequency itself. Adding about 200 for core + 500 for memory, can boost render results about 20% (I'm getting over 220 in OctaneBench with 1080ti, that scores ~ 180 out of the box). However to keep stability You might need to bump fan speeds or even go watercooling route.
Last but not least, if You're rendering in PT, there are couple of parameters in Path Tracing: Parallel Samples (8 by default) & Max. Tile Samples (16 by default) - crank those to max & Your GPU usage will increase about 5%.
Overall tuning for performance is not that hard, but nvidia done a great thing balancing compute performance with acoustic signature of GPUs, so they would make little to no noise under full laod. If You do not care about that or have aftermarket cooling system, then squeezing 95% under full laod is possible.
