JCIFS: file retrieval is too slow to be usable

java, jcifs, samba, windows-share

Solution

I found somewhere that SmbFileInputStream doesn't do its own buffering and hence the reason for being slow. Wrapping SmbFileInputStream in a BufferedInputStream solved the problem.

 SmbFile sFile = new SmbFile(path, authentication);

 BufferedInputStream buf = new BufferedInputStream(new SmbFileInputStream(sFile));

Problem

I was just testing JCIFS for accessing Windows shares. It is very slow to the point of being completely unusable. ``` import jcifs.smb.*; class First { public static void main(String[] args) throws Exception { try { //jcifs.Config.setProperty( "jcifs.netbios.wins", "192.168.1.220" ); NtlmPasswordAuthentication auth = new NtlmPasswordAuthentication("domain.com", "Administrator", "password"); SmbFile f = new SmbFile("smb://10.17.15.12/Share/xml/file.xml", auth); SmbFileInputStream in = new SmbFileInputStream(f); byte[] b = new byte[8192]; int n; while(( n = in.read( b )) > 0 ) { System.out.write( b, 0, n ); } } catch (SmbException smbe) { System.err.println(smbe.getNtStatus()); System.err.println(smbe.toString()); System.err.println(smbe.getCause()); } } } ``` It takes very long time for initial output to come and subsequent reads are also very slow. Any ideas how to use it? Any alternatives by which I can write Java code to access the Windows shares in a portable way are also welcome
