I think more comparable with Nazism would be Stalinizm. It didn't last that long(although the horrors done to the Soviet people in that short time are unimaginable). Most of Soviet Union's history and the Cold War is relatively calm if I just subjectively compare to our times.

Mass slaughter started well before Stalin, so at least 30+ years. What followed was calm compared to Stalin, or to North Korea, but nevertheless you wouldn't want to compare it to saner parts of the world.

When are you saying the slaughter started? 30 years pre-Stalin takes you back to before communist rule by my estimate, however there are a variety of points you can measure from.

Slaughter started with Lenin (not even counting the Civil War), so from the revolution to 1953 give you a bit over 30 years, give or take.
