FAST exporting, BUT after the export, the images that are added to the Catalog Makes all slow

Accepting each folder needs to have the files needed - can the team members not browse to, and carry out needed tasks with, that folder and those files directly? This is AFAICT why we export: to create derived image versions, themselves unsuitable for further editing work or changes of management, that will be accessible from outside the Catalog.

On the subject of fast export but slow re-import: is it possible these exports are merely fast to submit for queued processing? If they are then proceeding in the background, that would result in a delay before each file is made and then a re-import of that becomes possible. So this may accordingly present as fast export but slow import.

The way to be sure would be to separate export and import, and to verify in the file system how long it does take before exported files are completed. Then the import speed could be directly checked also. Also computer resources may be fully taken up with queued export processing, likely more computation-intensive than import would be.

Those times don't agree with mine. What size are your exports? How much free space do you have on the internal SSD?

Are you actually saying the 2-3 seconds happens as you scroll through the images that were added after the export?
