Directory listing speed regression with large numbers of folders #14775
Description
Describe the bug
Despite #14542, buckets with large numbers of 'folders' in the root take a long time to load in Cyberduck 8.6.0. The log shows that Cyberduck is calling b2_list_file_names for every 'folder' in the root of the bucket.
To Reproduce
Steps to reproduce the behavior:
- Create a bucket in B2 with tens of thousands of 'folders'.
- Browse around the bucket in Cyberduck 8.6.0 vs the previous 8.5.7.
Expected behavior
Listing bucket contents should be as fast as it was in prior versions
Desktop:
- OS: macOS
- Version 13.4

Log Files
As a test, I created 1,000 'folders' in a bucket. Cyberduck took 42 seconds to display the bucket listing.
