I've automated a deployment, and used 7-zip to compress a directory as part of the automation. Whenever 7-zip comes to compress the directory, however, it seems to take a long time (over 60 seconds) at the start when it just says "Scanning" ... it doesn't seem to be adding files to the archive at this time. Also, its not using significant CPU time.
It's not a big directory; maybe 8 MB, and not an overly large number of files - less than 300.
What's it doing? Should I be concerned? Can I speed it up?
