Granted I have new hardware but this month's parity check was flying! Major speed increase. All the drives & HBA are the same. Motherboard, (dual) CPU, RAM, and cache pool all new. What is odd is the first parity check last month on the new hardware was a minimal increase.

Did you update Unraid itself between the October and November parity checks?

I don't recall specifically, but I usually install both RC and stable releases within a couple days of release. While I built the new server, the old one was down so maybe 2-3 weeks? I vaguely recall installing a newer version on the trial key (and then on main usb once ready to bring it back online with new hardware) for testing new setup so yeah at least one version upgrade.
