Question

我正在使用JCIFS库从NAS位置获取文件。我的代码如下：

NtlmPasswordAuthentication auth = new NtlmPasswordAuthentication(domain, userName, password);

SmbFile sFile = new SmbFile(fileRecordId, auth);

jcifs.Config.setProperty("jcifs.smb.client.responseTimeout", "1200000");
jcifs.Config.setProperty("jcifs.smb.client.soTimeout", "1200000");
jcifs.Config.setProperty("jcifs.resolveOrder", "DNS");
jcifs.Config.setProperty("jcifs.util.loglevel", "3");
jcifs.Config.setProperty("jcifs.smb.client.dfs.disabled", "false");

LOG.debug("SmbFileInputStream");

BufferedInputStream inputStream = new BufferedInputStream(new SmbFileInputStream(sFile));
byte[] bytes = IOUtils.toByteArray(inputStream);

LOG.debug("fetched");

inputStream.close();

但是，对于1 MB的文件，从NAS提取将花费近1分钟，对于15 MB的文件，则需要花费15分钟左右。

我在JCIFS: file retrieval is too slow to be usable中尝试过解决方案

此外，在日志级别3中，我遇到了一堆以下异常：

但是文件正在下载。

为什么要花费这么长时间从NAS位置获取文件？

JCIFS Samba文件获取缓慢
