> These IMAP commands are slow when running against a big messages number:
>  * IMAP Store
>  * IMAP Copy
>  * IMAP Move
> This could be improved by:
>  * Change sequential handling -> concurrent handling (with Cassandra consistency condition)
>  * Increase copy and move batch size in `batchsize.properties`
>  
> Also, RENAME command has a consistency issue. We should consider using concatMap for it.
