SVNKit Export在java中需要比shell命令更长的时间导出＆＃39; svn export＆＃39;

Question

我正在制作一个程序，将我的存储库（或我的仓库的特定目录/文件）的内容导出到指定服务器上的目录中。我有基本的功能，但问题是速度。对于所有文件，我对这些导出的平均测试时间为193秒，而在linux shell中自己运行命令只需要大约6秒钟。我接近这个的方式有什么不对吗？

private boolean stageItems(SVNRepository repository, SVNUpdateClient 
                           updateClient, String server,
                           String version, ObservableList<String> items) throws SVNException {

    boolean success = false;
    long totalDuration = 0;
    String baseUrlPath = "http://" + repository.getLocation().getHost() + repository.getLocation().getPath()
            + "/branches/versions/" + version;

    Iterator<String> itemItr = items.iterator();
    while (itemItr.hasNext()) {
        long startTime = System.nanoTime() / 1000000;
        String item = itemItr.next();

        String fullPath = baseUrlPath + "/" + item;
        SVNURL url = SVNURL.parseURIEncoded(fullPath);

        SVNNodeKind nodeKind = repository.checkPath("/branches/versions/" + version + "/" + item, -1);

        File destPath = new File("\\\\" + server + "\\u1\\pyle\\team\\moy\\bbjstaging\\" + item);

        if (nodeKind == SVNNodeKind.DIR) {
            long l = updateClient.doExport(url, destPath, SVNRevision.HEAD,
                    SVNRevision.HEAD, null, true, SVNDepth.INFINITY);
        } else {
            long l = updateClient.doExport(url, destPath, SVNRevision.HEAD,
                    SVNRevision.HEAD, null, true, SVNDepth.EMPTY);
        }

    }
    return success;
}
