I'm using Exiv2 to parse JPEG files (JPEG only actually). 

Exiv2 isn't based on JPEG lib. I suppose that this point is optimum. No need 
to initiate a JPEG image decoder to only extract metadata. Nota : the old 
Renchi's implementation use libjpeg (0.8.x).

Note that Exiv2 support CRW file and in the future all TIFF/EP file like.
This is want mean that the startup time will be decrease, but capabilities to 
search an image using metadata will not be limited to JPEG files, but all 
major RAW files format (NEF, DNG, etc.) supported by Exiv2 ! Look my recent 
screenshot here :

But nothing is planed to do that for 0.9.0. About file parsing at startup, all 
work like 0.8.x serie, excepted some optimizations.

Also, Marcel have also doing a great job about optimizations during startup to 
clean up all process loop. Look this file in B.K.O:
