Recently optimised mjminer plotter to produce fully optimised plots directly. Use same arguments as usual but prepend with sudo, it just produces fully optimised plot files:
https://github.com/k06a/mjminer
It requires root access because of fast file allocation without zeroing its content – which is potentially not safe, because app will be able to access data of deleted files. But in case of plotter it is not a problem – files gets allocated, then is fully rewritten. You can read all changes in this pull request:

I wanna this PR to be merged into original repository. Do anyone have contact of @r-majere?
