Is there a reason 64bit mode of cyberduck uses so much more memory? It uses around 40mb more memory then the 32bit mode of it.

This is expected.

The memory usage of a 64-bit application may be significantly larger than for a 32-bit version of the same application. The difference in usage varies from application to application depending on what percentage of data structures contain data members that are larger in a 64-bit process.

In the Cyberduck package Info.plist, we have a LSArchitecturePriority setting that prefers 32bit mode when launching the application, therefore the Open in 32-bit mode is checked by default in the Finder for launch services. See wiki page.
