[OpenDroneMap-users] How to adjust processing parameters based on quality requirements

Dear colleagues,
First, congratulations for the development of OpenDroneMap project. I just install OpenDroneMap in a Linux machine and I need some help to choose the parameters to perform a low, normal or high quality processing. The images were acquired with inpireOne DJI drone (4K camera, gimbal). I have 42 aerial images with  12M pixels  (3992 x 2992), jpeg, geoTagged, captured at 60m height, ground sample distance (GSD) of 2.5cm / pixel. 
I guess the processing quality parameters are: --resize-to--use-opensfm--min-num-features--matcher-threshold--matcher-ratio--matcher-neighbors--matcher-distance--cmvs-maxImages--pmvs-level--pmvs-csize--pmvs-threshold--pmvs-wsize--pmvs-minImageNum--odm_meshing-maxVertexCount--odm_meshing-octreeDepth--odm_meshing-samplesPerNode--odm_meshing-solverDivide--odm_texturing-textureResolution--odm_texturing-textureWithSize--odm_orthophoto-resolution
I do not know the details behind the algoritms, but I want to tune the parameters to processing my set of images in low (quick), normal (standard) or high (slow) quality results. Can you help me? I know theses terms 'low', 'normal', 'high' are very subjective. But I need know a way to fine tuning the processing for show the results, compare it with other softwares, eg Pix4D, etc.
I am running  in a machine with Linux, Debian 8, amd64, with 12 processors (Intel Xeon 2.3Ghz), 32GB RAM. It is a HP Z820 workstation.
Thank you,Khyale
