It said it was "building profile with (some number) pac= kages", and it took at least 2 minutes on that stage only no > matter the size of the package. This is surprisingly long, indeed. Do you use an SSD or a rotating disk? As Felix mentioned, the latter is likely to be quite slow for these operations. Also, the duration of this operation depends on the number of packages in the profile, and more or less on the number of files involved. It would help if you could reproduce the slowness with as few packages as possible to see if we can identify some pathological behavior. Thanks, Ludo=E2=80=99.
