Please advise how I might be able to speed up the responsiveness of the program.

Thank you.
Which Operating System do you use, what type of interface is the external drive connected to, and how is it formatted? And, which calibre functions are unresponsive… e.g. starting, sorting searching, conversion, viewing, book editing etc?

I have a 1.3TB 150,000 'book' calibre library (video and audio clips) on an external USB 3.0 HDD drive, I can't discern any performance differential between it and my 4,000 book calibre 3.1GB library that sits on an internal SATA 3.x HDD drive… e.g. switching between them is sub 3 seconds either way.

For Old Curiosities sake I transferred my Books library onto my SDD, once again I couldn't discern any performance differential.

calibre is closer to Cairo than Giza.
