Please be aware that the SF Farms Power system uses a huge amount of script time. Quintonia Farms version, alse the SF Shower.

A while back her animals caused huge amounts of MySQL writes due a writing a notecard endlessly. Possibly the same thing as a grid I am helping fix is running 30 to 40 megabytes a second writes and is very very slow.

Open the Resource Monitor and look for excession disk writes by MySQL.
