OK thank you. I'm going to do some tests and see the results.

The problem is that whenever I place the BandwidthRate and BandwidthBurst above 10MB I lose the Guard, HSdir and V2Dir flags. On the page
https://metrics.torproject.org/rs.html#search/TugaOnion I see that DirPort is 0 instead of 9030. I have the BandwidthRate and BandwidthBurst at 9MB and everything is fine, but I will reach the end of the month and I only spent about 10TB.
