Can this encode faster with a lower filesize?

program --level 4.1 --preset slow --crf 20.0 --keyint infinite --min-keyint 1 --scenecut 60 --qpmin 10 --qpmax 51 --chroma-qp-offset -12 --partitions all --psy-rd 2.00:2.05 --output "output" "input"

Can this be modified to encode faster somehow with a lower filesize?

Something like this:
program --level 4.1 --preset medium --crf 21.0 --keyint infinite --min-keyint 1 --scenecut 60 --qpmin 10 --qpmax 51 --chroma-qp-offset -12 --psy-rd 2.00:2.05 --output "output" "input"
or
program --level 4.1 --preset fast --crf 23.0 --keyint infinite --min-keyint 1 --scenecut 60 --qpmin 10 --qpmax 51 --chroma-qp-offset -12 --psy-rd 2.00:2.05 --output "output" "input"

Note that encoding to a lower bitrate/higher CRF with everything else the same will also encode somewhat faster. Fewer bits means less to run through CABAC, etcetera.

The original command line seems rather over-specified, though. Some unusual source or something?
