I started a project processing several days ago with a custom resolution of 1.5 inches per pixel (3.81cm/pixel) and it seems to have increased my processing time significantly. Previously I was used the automatic setting with a multiple of 1x GSD which was somewhere between 1 and 1.5 cm/pixel for a project that was a bit larger (3600 photos versus the 2600 used for the auto setting). The processing time for the project with 3600 photos took around 3 days. Currently I am only in step 2 of the project with 2600 photos and it has been 4 days. The only other difference was that my output setting for accuracy was 0.08 ft in the 3600 photo project and 0.02 ft in the 2600 photo project (since I needed a bit more accuracy).
Does the custom resolution slow the processing time?
Or alternatively is there something else going on that I should look into?
Is it the accuracy setting the thing that is slowing my processing time? If so, how can I maintain accuracy and decrease my processing time?
