11 At the extreme of all ChangeLog moved in old there are 10371 more files
12 in the tree, 25 MB less to check and to transfer (in case all the
13 Changelogs are modified at the same time).
14
15 In a more general scenario, only about 1300 Changelogs need to be
16 transferred in ChangeLog.old, Leaving The total size of the Changelogs
17 to about 18 MB instead of 25, with about 6 MB in ChangeLog.old (assuming
18 no duplicated data).
19 The Total number of ChangeLog* raise to 10371[norm] + 1365[.old] = 11736

21 There is a overhead for user that not use rsync exclude and a noticeable
22 gain for user that instead exclude ChangeLog.old .
