The deleting of the mails goes also same speed, much much much slower then any mail client software can act. And this one is not the fastest communication mean, the mails need to be called up one by one regardless of mail client. But then all progs must be same, since the protocol used (POP3) is same in both cases. OK, when you the storage on the usb stick, there is a speed limit in how fast this can be stored on the stick. Hmm, I dont think you really find any mail program being slow or fast.
