mac encryption and AFNI scripts

Looking for wisdom on the AFNI x encryption interaction - Anyone noticed a change in script speed and output after encrypting? I’m getting a new computer up and running and would love some input on a security option that doesn’t slow down large dataset scripts (if that’s even a real concern)…

Any thoughts are appreciated!

Encryption will slow things down somewhat, but I don’t have any figures (as all NIH systems are required to use encrypted drives).
You can speed things up at the cost of using more disk space by setting various environment variables (e.g., in your .afnirc or .cshrc files)


These will prevent AFNI from compressing output datasets, which will be faster both on output and on input.
