I would like to know a practicality of the MMCAU. Have anyone applied the MMCAU to real applications (e.g. SSL communication)? In such case, is the performance enough? I'm afraid the MMCAU cannot be applied to real applications because of its (probably) low performance. The background of this question is that I was told by my friend who has used the MMCAU for SSL communication says that the MMCAU performance had been very low. Can anyone correct me if he has good experience?
