Now that I've played around with Calibre to become a little bit familiar with how to use it, I'm beginning to populate its library with the hundreds of books I've downloaded from various places such as MobileRead, Feedbooks, Baen, and Project Gutenberg. At this time, I have 432 books in my library -- including the supplied Quick Start Guide.

I've noticed that any interaction with the library -- even if it's only editing the metadata for a single book -- goes abysmally slowly now. Much more slowly than when I first started loading books into the library. Opening a small ePub can take minutes. Adding 10 books may take as much as 20 minutes.

Some info: using Calibre Portable 1.39.0 on a 128G USB 3.0 thumb drive. I have some plug-ins installed ... will be glad to list them if someone thinks that the plug-ins could be causing the performance problem.

On the Windows 7 system I am using, all drives are connected via USB except the {very small} boot drive. I wouldn't expect to get any better performance by moving the program and library onto another drive ... unless Windows 7 uses different rules for buffering drives it perceives as regular drives versus those it identifies as "devices with removable storage" -- that is, the thumb drive.

I'd appreciate any help -- from Calibre experts and/or Windows experts.
1) USB Flash drives are slow
2) Is the drive connecting at the old USB1 speed
3) is your anti-virus scanning

I have used a USB Hard drive (old Laptop drive in a caddy), Performance is only a tiny bit slower than a Local SATA drive. 4000 books

10 books on an old P4 running XP is under a minute
