I'm working with the latest version of PS in Windows 10, processing very large files (e.g., 35+GB) on a very capable computer (e.g., 96GB RAM). When I perform certain operations, like duplicating a layer from one .psb file into another or converting a smart object to layers, PS sometimes performs the operation almost instantaneously. At other times, PS will cycle several times through a series of loading>preparing>scaling>preprocessing operations, often taking several minutes. I can't identify any trigger that differentiates the instantaneous vs. the long-cycle operation. Does anyone know if there is any way to circumvent these endless processing cycles?
Thanks for the reply. I know history states chew up scratch disks rapidly. What puzzles me is the inconsistency. I don't understand why, e.g., I can duplicate a layer almost instantaneously at one point but, next time I try it, it may take 4-5 minutes. The difference is not attributable to the one layer being simple and the other complex (filters, etc.). Let me try disabling First Snapshot. That seems like it might play a role. Thanks, again.
