I just spent the last couple hours playing with it and am puzzled. I moved the metadata.db file and created a soft link it on the the pci-e flash drive that has 600 mgs a sec through put and didn't see much performance increase over the 140 meg a second sata drive in searching or doing a search.

Moved the file to a ram drive tmpfs under /tmp on ubuntu and the speed of starting calibre was very contemporary to both the hard drive and the ssd pci-e card, same for the search. So..... im confused. the ram drive is throughput can be measured in gigs a second vs 100 to 100's of megs a second but im not seeing much speed improvement at all.
