Through testing, it was found that the slow loading of file directories is
due to the following method（class is:
org.apache.sshd.sftp.server.AbstractSftpSubsystemHelper）：
The first place：**Map<String, ?> attrs = resolveFileAttributes(f,
SftpConstants.SSH_FILEXFER_ATTR_ALL, !followLinks, options);**, it takes 6-7
milliseconds each time.
Second place: **accessor.putRemoteFileName(this, f, buffer, shortName,
true);**, it takes 5-6 milliseconds each time.
```
protected void writeDirEntry(
int id, DirectoryHandle dir, Map<String, Path> entries, Buffer
buffer,
int index, Path f, String shortName, LinkOption... options)
throws IOException {
boolean followLinks =
resolvePathResolutionFollowLinks(SftpConstants.SSH_FXP_READDIR, "", f);
Map<String, ?> attrs = resolveFileAttributes(
f, SftpConstants.SSH_FILEXFER_ATTR_ALL, !followLinks,
options);
entries.put(shortName, f);
SftpFileSystemAccessor accessor = getFileSystemAccessor();
ServerSession session = getServerSession();
accessor.putRemoteFileName(this, f, buffer, shortName, true);
int version = getVersion();
if (version == SftpConstants.SFTP_V3) {
String longName = getLongName(f, shortName, options);
accessor.putRemoteFileName(this, f, buffer, longName, false);
if (log.isTraceEnabled()) {
log.trace("writeDirEntry({} id={})[{}] - {} [{}]: {}",
session, id, index, shortName, longName, attrs);
}
} else {
if (log.isTraceEnabled()) {
log.trace("writeDirEntry({} id={})[{}] - {}: {}", session,
id, index, shortName, attrs);
}
}
writeAttrs(buffer, attrs);
}
```
