I’m using the latest version of Firefox, on a Windows 10 PC. CNC probably has made it worse this weekend, but it’s always really slow, on the order of 3-4 minutes per observation. i usually get everything else done and go away and do something else for a while.
Out of curiosity, would the number of obs in the batch affect the per obs speed? I tend to work in batches of 10 or more. Dangerous, since much can go wrong, but there it is!
