I am running OXS with 8gb RAM and two 2.26 Quad Zeons. I am experiencing HEAVY spiking in CPU utilization, upwards of 800% even when making small adjustments such as reducing the blacks by ONE increment. I am now running of an exported catalog with about 15 images w/ previews. Both the cat and images are on the same HDD as lightroom is installed on....WTF is going on. Never used to be this slow.
Write xmp data is off.
appreciate any help!
thanks
