Performance problems while getting all dirs from a repository

Hello all,

to get all directories from a repository I use the following code:

public List getReposTree() throws DataProviderException {
     SVNLogClient logClient = new SVNLogClient(this.repository.getAuthenticationManager(), new DefaultSVNOptions());
     final List<SVNDirEntry> entries = new LinkedList();
     try {
                        logClient.doList(this.repository.getLocation(), SVNRevision.HEAD, SVNRevision.HEAD,
                        false,
                          true, new ISVNDirEntryHandler() {
                              public void handleDirEntry(SVNDirEntry entry) throws SVNException {
                                  entries.add(entry);
                              }
                          });
                } catch (SVNException e) {
                        e.printStackTrace();
                }
                return entries;
    }


Is there a way to speed up this function?

At the moment my repository is not very big, but this function needs 5 seconds to finish.


Thanks for any help,
