Catalog Metadata Gathering -- Speed Estimates seem strange

[Bob Hendricks]

When one is adding items to a catalog, the "Catalog Metadata Gathering" info seems strange.  In my case, with a few thousand images to catalog, the estimate is something the order of 6 hours.  However, the process run-in perhaps 20-30 minutes. The time is taken off the time estimate really quickly and it runs down 0 at the time when all of the images have been cataloged.  It appears that the time estimate does not correctly calculate for the number of processors and the speed of those processors.

Hi Bob,

That's indeed strange. What type of drive are the images on? (E.g. network drive? External HDD?)

The rate and its associated completion estimate is calculated based on a historical average; a sliding window covering the last 200 or so batches pulled from the queue.


Regards,

Bill

I am running OS 14.6 (Mojave) on a  late 2012 iMac with a 3.2 GHz  Intel Core 7 processor. The hard disk is is an external 4T Western Digital dual drive  VelociRaptor with Thunderbolt 2 cable.  This is about as fast as possible with such an old machine.
