For the record, my Glo HD takes less than 2 minutes with nearly 5000 books. I have had reason to connect with the metadata.calibre, and that was still less than five minutes.

It will take longer if there are a lot of changes in the collections of series. I did change the collections management settings last night and the next connect on the Glo HD took about 8 minutes in the "Sending metadata to device" job. That was because it removed a lot of collections.

It is possible the issue is the database on the device. If it is corrupt, this can take longer. But, usually if it is bad enough to cause performance problems, it will raise an error when calibre is accessing it. If you have my Kobo Utilities plugin installed, you can check the database with it. That also has a compress option which will reorganise the database and can help performance.

The only other things I can think of is if something else is access the device at the same time. A virus/malware scanner would be the obvious thing. Or if the device was being mounted as a USB1 device instead of USB2. That would slow things down.
Hi,

Thanks for the response.

What is your plugin and how can I get it ?

Thanks
