107,000 songs test

my library was 107,000. tried to run it in hole block. I have imac i7, thin one 32gb ram, fusion -> took about 5 minutes to sort it all out in terms of duplicates, few seconds to filter it,
based on result I had about 45,000 dplicates of which according to app, 25,000 were identical,
about 20 hrs to delete, I picked filtering based on bit rate. honestly was not that big of issue as let it run on background.
note: my library (the one filled with duplicate is already backed up) and software was examining music on external DNS server.
I think this process might have slowed down deleting process as imac is still not properly connected to server (imac to wi-fi, wi-fi to server via ethernet)
re-run test and app was showing about 500 leftover dups.
deleted and reduced to about 200 which seems like app is not confortable in deleting any further
thought itunes library would have had to be reconstructed.
but seems like on second look at it that the duplicates are actually what I was hoping software would have left intact: same song, same bit -rate, different album (or what unfortunately happens with old library like mine (albums that were originally copied into HD with incorrect naming) which result in same song, same bit-rate, same time but inproperly registered album name or track name… minor issue
anyway… maybe Im gonna take it all back tomorrow (maybe not cuz I still my full old library backed up) but to me, software did a pretty excellent job.
