Hi, I’m not with PM support, but I've faced this issue and thought I’d share something that helped me. Assuming that you’re running an anti-virus program, see if you can setup an “exclude” exception on the file types you ingest. For me, this is NEF (Nikon’s raw file format), JPG, XMP and several Capture One file types.
For example, in Bitdefender, I have excluded those file types from “on-access” scans (AV scans that happen when a file is accessed) plus I’ve turned off all AV scans on “Flash Drives” (my card reader & camera's memory cards). If you’re using another AV package, hopefully it has similar options.
I saw a dramatic improvement in ingest performance thereafter. And while there *is* some increased risk of infection with some scanning turned off, the risk is worth the reward in my use case.
