Unfortunately, 0.3.2.9 does not have the DDoS feature.

And please disable CellStatistics and ConnDirectionStatistics.

We could give you better advice if you posted your machine specs

The combination of DDoS defence and turning off statistics dropped my
(Linux) relay RAM usage from 6-10 GB to about 1 GB.
