Looking at your post, You are already using the best format. If you do not have a fast filesystem try making a ram disk and play the files from there instead.
if you *really* want you can use sox to turn them all into raw alaw files and rename them with a .PCMA extension to avoid the g711 transconding but g711 to PCM is pretty trivial. it's more likely a file i/o distress you see.
