A 5x reduction in RAM usage with Zoekt memory optimizations

N times less usually just means it uses 1/N. So this would mean it uses only 20% of the memory it used originally.

Yeah it doesn’t make sense as the x in 5x I would have thought repetesents a multiplication rather than (divide)

It would make more sense for me to say a fifth, or 1/5

    log(5x)  =  log(5) + log(x)
    log(x/5) = -log(5) + log(x)

So the difference is just a sign change on a log scale. And it's natural to use a log scale when working with percentage changes.

Natural for who?

Perhaps better expressed as “5 fold”.
