So that is 5 to 4 times overcommit of virtual memory. It probably only gets 4-6G physical memory. Of course, C1 doesn't get all 8 to itself. Memory use of C1 is about 24G on an 8G machine. It looked like it would take only around 3 hours. Images were ticking off at a rate of 6-8 a second. Ratings and crops were enough-anything more is a bonus. I began to import the catalog into Capture One. Now I have a nice LR catalog pointing at referenced images on an ssd. I should have purged many keywords, but I didn't realize what a problem that would be. Did a little bit of clean up on the LR catalog: creating static albums out of smart albums and deleting a few unnecessary albums. I later had to do the same thing in C1: more than 1/2 of an hour. Relocating in LR-well I looked away from the screen for a second and didn't know it had even completed. Copied everything from the main machine internal drive to an external ssd. I decided to transfer the LR catalog to C1. Using tokens, it was easy to use the import to generate a hierarchy of folders that fit the structure of the referenced image catalog. I'd used the location metadata field for the subject matter-easy to copy across all of the images in a folder. The session folders were on an external SSD so it was easy to import images with adjustments into the new catalog back home. Most of the work to cull and edit was done during the trip. I went on a trip and shot 1300 or so pics that went into about 9 sessions. I started putting new work into a catalog and left my LR catalog in place. I recently made a commitment to C1 and purchased it.
