Hi Karl, 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. I suppose, WINS is used when accessing hosts on different subnets. Another suggestion for similar problem from another example[2]: "-Djcifs.resolveOrder = DNS" Finally; I suggest these changes: Remove the line (System.setProperty("jcifs.resolveOrder","LMHOSTS,DNS,WINS"); ) from SharedDriveConnector.java Add "-Djcifs.resolveOrder = LMHOSTS,DNS,WINS" to "start-options.env" file. If you have been convinced about this, I can create a PR.
