I am wondering if anyone else is seeing this issue. I have some very large projects (one is 18TB) that are almost exclusively RED .r3d. Monstro, Helium, and Komodo, (some projects also have Scarlet-MX). When I set to optimized or original (I never optimize) I get pretty good performance on an fully kitted 2013 Trashcan. I have 4 G-Speed Shuttles, 48, 64, 96 and 144 TBs that are running thunderbolt 2 and are set to RAID 5 I get about 1200 MB/sec read and write. But when I switch over to proxy, i get massive slowdowns. I have tried keeping the proxies in the library, as well as in a separate folder. Still, massive slowdowns. Beach Ball City. I have never seen this before. I am on FCPX 10.5.3, and macOS Big Sur 11.4. I am also using RED's latest Apple workflow plug-in 18.2.0. Thoughts?
