> Current implementation of FTP and SFTP filesystems have severe limitations and performance
issues when dealing with high number of files. Mine patch solve those issues and integrate
both filesystems such a way that most of the core functionality is common for both and therefore
simplifying the maintainability.
> The core features:
> * Support for HTTP/SOCKS proxies
> * Support for passive FTP
> * Support for explicit FTPS (SSL/TLS)
> * Support of connection pooling - new connection is not created for every single command
but reused from the pool.
> For huge number of files it shows order of magnitude performance improvement over not
pooled connections.
> * Caching of directory trees. For ftp you always need to list whole directory whenever
you ask information about particular file.
> Again for huge number of files it shows order of magnitude performance improvement over
not cached connections.
> * Support of keep alive (NOOP) messages to avoid connection drops
> * Support for Unix style or regexp wildcard glob - useful for listing a particular files
across whole directory tree
> * Support for reestablishing broken ftp data transfers - can happen surprisingly often
