[jboss-user] [JNDI/Naming/Network] - very slow connection from client to server
Hi,
why does the client always needs so much time (about 5-10 seconds) to get a connection to
the jboss server? Even if I try to connect to the server the second or third time.
The client runs on a Windows-System, the JBoss-Server on a Linux-System.
If I do the same things with JBoss on Windows all works fine.
