Hello all,

As you can see from the attached conf, I use Redis to store bayes and 
auto-whitelist data. Primarily because I operate on macOS and the disk based db 
storage doesn’t work on APFS.

I recently enabled TxRep. However, enabling it increases the time and resources 
(memory and CPU load) spent exponentially. For example, when I run 'sa-learn 
—spam —mbox /my/mail.mbox' to a mailbox with 1000-2000 messages, it typically 
takes 1-2 minutes to finish. Setting use_txrep=1 bumps it up to 20-40 minutes 
while also consuming significantly more memory and CPU.

Is this normal or am I doing something wrong?
