Hello
When Mbox Split feature was not implemented, I wrote a code and comparing it with your new 24.6 split method, yours seems to be about 10 times slower!
May I share my code so you kindly pass it to the devs. might …... Olm extraction, about 5 times slower! Nsf extraction, about...about 8 times slower! Tgz extraction, not much but still some! Thanks...
