Daniel,

I don't have the answer, but this article (for instance) suggests the
opposite, even for a legacy Ubuntu release.

Are you sure all the cores are running at full speed? (Right click the
top panel and add "CPU Frequency Scaling Monitoring" - ou como quer
que isso se chame em português - one for each core). Do you have a
reasonable amount of free space in your partitions or you packed all
the Linux stuff in a tight space right at the end of the HD? Perhaps
the journaling process on a NTFS to ext4 copy is taking its toll
compared to a NTFS to NTFS copy. Are you copying or moving (copy and
delete) files?

Since I don't have any real Windows installed any more, I cannot test
this on my stations, perhaps someone else can.

Abraço,

Lucio

P.S.: Never say sorry, (at least, not in advance).
