Comment 2 for bug 738310

Hello, smbnetfs delay might be related to libsmbclient name resolution procedure.
By default libsmbclient tries to resolve names via lmhosts file, dns, wins and broadcast.
libsmbclient tries each resolution method for each configured network interface. So the
network name resolution may takes a a very looooooong time.

Try access files using ip-address instead of computer names
  1) mount smbnetfs via command "smbnetfs /media/SMB"
  2) access files using the following path "/media/SMB/192.168.1.99/TESTE"

If the problem disappear, you may do the following:
  1) Fix libsmbclient name resolution procedure. You may play with "name resolve order",
      "interfaces" and "bind interfaces only = Yes" options in your ~/.smb/smb.conf file.
      See "man smb.conf" for details.
  2) use "link" directive in your "~/.smb/smbnetfs.conf" file to access all required
      computer by their ip-address. See smbnetfs documentation for details.
