A good starting point would be 512mb, then move up or down to determine optimal value, measure throughput or response times, and analyze GC logs to understand frequency and length of scavenges.

Considering an increasing frequency starting from some arbitrarily low value, the "gain" of the circuit is initially the same as an unbypassed cathode circuit.

These show that vegetation dam can reduce starting drag force and starting frequency of sediment in upper reaches. And can make athletic sediment deposit.
