I ran my cutterhead at full tilt for years before a pump failure in Galveston showed me why that's dumb.
We lost suction on a big channel job because I was chewing up material too fast for the pumps to keep up, which overheated the whole system. The foreman pointed at the temp gauge and said, 'You're feeding a fire hose with a bucket.' How do you guys find that sweet spot between cutter speed and pump flow on different soils?

Ouch, that's a rough way to learn. I usually start by backing the cutter off until the pump pressure looks happy, then creep it up. It's all about watching that suction gauge more than the dirt.
