Tranfer extremely slow when using "compare" option

[cyberduck]

6ec3a22 created the issue

I want to tranfer files from a remote storage unit to a local HD using the "compare" option. Up to the previous version of Cyberduck it worked fine and fast.
Now, "comparison" (preparation) is extremely slow: some folders/files that have NOT been changed, and that are thus identical both on my local HD and on the remote storage unit, are "compared/prepared" very slowly. The "comparion slowness" does not seem to be related to the size of the files/folders examined.
The problem is reproduclble: after a first slow comparison/transfer, a second comparison/transfer is again slow on some folders (probably the same folders) and no transfer is done as expected.
The problem is not encountered when the option "ignore" is used: name checking is made within a few seconds, whereas "comparison" requires about 10 minutes for the same set of files and folders. Is there a problem upon checking of size, modification date, or checksum?
NB: The complete set of files/folders to be examined is 85GB, and was about the same when I was using the previous version of Cyberduck about 10 days ago.

I read ticket #11676 and I reinstalled version 7.8.5: transfer with "compare" option works again fine and fast.
