I have a brand new HP Z820 loaded with 64GB ram, 2x8 core at 3.1GHZ processors a Quadro 4000 and a Telsa C2075. Next to it sits a 2.5ghz single processor imac (4 cores) with 4GB of ram. I have the same R3D loaded into each and the imac scrubs through the shot in the viewer much faster than the HP and just feels zippier. Any clues as to why? Haven't really changed any configuration in the HP since I got it. The R3D's are on a pretty fast thunderbolt external in the imac the HP just has a couple internal drives software raided while I wait for the proper raid I have ordered to turn up. Even if I copy the R3D onto the system SSD which is very fast it still clunks along. Even after the shot is completely cached into Ram the playhead lags severely behind the mouse pointer when I drag it along the play bar.
I am very confused and somewhat disappointed. Obviously the machine is extremely powerful and I am sure there must be something I am doing wrong but can't figure out what I need to get it to work properly with Redcine-X Pro as I haven't had to do anything to the mac version and it works fine on the imac.
Thanks for any advice.
