On some systems bmp will load faster than jpg as HD burst acess can be pretty good, and there's no decompression to do - it's all a matter of internal memory formats and the variable speed of your hard disks seek time. The actuall IDE bus transfer is pretty quick.
I use tga in development, but i've now got my own disk format for when I make stuff public. It compresses almost aswell as jpg and is lossless, the hit is on loading times although isn't too bad ... The real slow bit is saving the images to the format in the first place as I didn't optimise that.
