Some analyses run very slowly over the network. This is mainly due to slow write times where spm SPM functions write slice-by-slice. The slow-down depends on network traffic and the number of people accessing the files. The intensive network writing can also cause file errors.
The A local processing option is implemented in some functions.

fMRI slice timing | Example at UCLA: slice timing over 420 HCP files Network: 5840 seconds Local: 620 seconds |
fMRI Drifter | Less important since 2022 speed-up (reading volumes) |
fMRI smoothing | Example at UCLA: smoothing 420 HCP fMRI files Network: 1200 seconds Local: 390 seconds (3 x speed-up) |
