RAM makes a difference, 2018.12.3 has a bad memory leak, and you can run apple hardware test on your work computer (extended) which will take over an hour to complete. If you really want to test, take the 64GB from your home computer and install it on your work computer and see if that's the big difference.

Now for the archival ungraded master that is unrendered it's bouncing around 12 to 14 hours and the whole system gets latent and virtually unusable. I tried reformating the Graid 20TB target drive with and the result did not improve much.I then copied all the media for the project onto a single 4TB Hitachi Deskstar and took it home. Running the Hitachi drive as source and going to the same Graid as at work the time estimate is about 4hours and 15 minutes and the overall system is snappy as hell. I did notice on the work system that Avid memory use was at times slamming up to close to 22GB or ram and the red memory pressure was showing a lot of red. I've done this before on this system with an unrendered archival master and there was memory pressure indicated but the system didn't grind to a halt. Could ram make that much of a difference. I see at home Avid is using 36.85GB memory along with kernal task at 2.82GB, AvidOPFrameGeneratorApp 1.084GB and AVid DMFSupportSvc 866.9MB.I would think at work with source media coming off a 16 drive san chassis connected through 4Gig fibre would supply data faster than a single spinning HD. At least the spinning HD isn't very fragmented. I'm wondering why the big difference between systems. I had asked for 64GB ram on the work system but they balked at investing in old tech. I don't know what else it could be. The only other thing is I replaced the Radeon 5770GPU in the work tower with a GTX-680 flashed for mac from another system. I've done a couple 4K shows since that swap without this issue and this timeline is simpler than most of the other shows.I wonder if the ram is getting wonky or the fibre card or Gpu. Anybody got a suggestion on what a good hardware diagnostic to run. I might have disk warrior on the system but are there some built in utilities that might check ram etc...?John Moore Barking Trout Productions Studio City, CA bigfish@pacbell.net
