Cihad Guzel updated CONNECTORS-1588:
------------------------------------
    Description: 
In some cases, "jcifs" is running slowly. In order to solve this problem, we 
need to set custom some properties. 
  
 For example; my problem was in my test environment: I have a windows server 
and an ubuntu server in same network in AWS EC2 Service. The windows server has 
Active Directory service, DNS Server and shared folder while the ubuntu server 
has some instance such as manifoldcf, an db instance and solr. 
  
 If the DNS settings are not defined on the ubuntu server, jcifs runs slowly. 
Because the default resolver order is set as 'LMHOSTS,DNS,WINS'. It means[1] ; 
firstly "jcifs" checks '/etc/hosts' files for linux/unix server'', then it 
checks the DNS server. In my opinion, the linux server doesn't recognize the 
DNS server and threads are waiting for every file for access to read.
  
 I suppose, WINS is used when accessing hosts on different subnets. So, I have 
set "jcifs.resolveOrder = WINS" and my problem has been FIXED. 
  
 Another suggestion for similar problem from [another 
example|https://stackoverflow.com/a/18837754] : "-Djcifs.resolveOrder = DNS"
  
 We need to set custom resolveOrder variable.
