Thanks for your answer. Cryptomator is version 1.4.15 and Dodanky is 1.3.0.1000
I tried with the user defined options for dokany as suggested by you and the results are - worse! Write performance is now only 1/2 of the already minimal speed I got with the default dokany options and the results for CrystalDiskMark6 and Parkdale again are fully in line. This time I shut down ALL other running programs and apps, including any antivirus and other “offerings”.
For simplicity’s sake here is a copy and paste of the results from CrytalDiskMark6 and from Parkdale for these settings:
