JCIFS讀取遠程服務器文件過慢的解決方法

與windows explorer打開相同的文件相比，JCIFS默認狀況下要慢太多了。我找了大半天，總算找出瞭解決方法，增長以下配置，則讀取速度會有質的飛躍，我這邊從7s提高至0.2s：

System.setProperty("jcifs.smb.client.dfs.disabled", "true");

至於緣由嘛，我也不知道，我是今後網站撈到的一條配置：

執行程序代碼以下：

private static final int BUFFER_SIZE = 1024;

public static void main(String[]args) throws Exception {
	//SmbFile file = new SmbFile("smb://finchina;daieel:123456@192.168.100.246/Soft/sc8 key.txt");
	//SmbFile file = new SmbFile("smb://10.15.97.181/xx部資料庫/工做文檔/查詢邏輯.txt");d
	//http://samba.2283325.n4.nabble.com/Peformance-questions-td4644647.html
    System.setProperty("jcifs.smb.client.dfs.disabled", "true");
       
	long startTime = System.currentTimeMillis();
	UniAddress dc = UniAddress.getByName("192.168.100.5");  
	NtlmPasswordAuthentication authentication = new NtlmPasswordAuthentication("fgina", "xiajl", "orange");  
	SmbSession.logon(dc, authentication);  
	SmbFile file = new SmbFile("smb://192.168.100.5/edse/users.txt",  authentication);  
	
	ByteArrayOutputStream out = new ByteArrayOutputStream();
	BufferedInputStream in = new BufferedInputStream(new SmbFileInputStream(file));
	//SmbFileInputStream in = new SmbFileInputStream(file) ;  //創建smb文件輸入流
	byte buffer[] = new byte[BUFFER_SIZE] ;
	int count = -1; 
	while((count = in.read(buffer,0,BUFFER_SIZE)) != -1) {
		out.write(buffer, 0, count);
	}
	String content = new String(out.toByteArray(),"GBK");
    in.close();
    System.out.println(System.currentTimeMillis() - startTime);
    
    System.out.println(content);
}
