The fastest access to the sd drive is via sdmmc: However I never had any performance issues using the SD library,
So maybe there are some issues with your SD card ?

For mp3 I am usually recommending libhelix.
I noticed that you left the log level at Info: did you try to set it to Warning as recommended ?

Further info can be found here....
