The rough pump seems to take a long time to reach the crossover point.  Once the gate valve is open, the system seems to pump fine.
Also, the power supply is making an audible clicking noise when it is turned on.  Once the power supply has reached the setpoint, there is no more noise.  It doesn't seem serious, but I don't ever remember hearing the power supply before.
