.BI "-g" delta ", --min-gain=" delta

Since the balancing algorithm can sometimes result in just very tiny

improvements, that bring less gain that they cost in relocation time,

this parameter (defaulting to 0.01) represents the minimum gain we

require during a step, to continue balancing.

.BI "--min-gain-limit=" threshold

The above min-gain option will only take effect if the cluster score

is already below \fIthreshold\fR (defaults to 0.1). The rationale

behind this setting is that at high cluster scores (badly balanced

clusters), we don't want to abort the rebalance too quickly, as later

gains might still be significant. However, under the threshold, the

total gain is only the threshold value, so we can exit early.
