> Avoid excessive calls to InetAddress.getLocalHost()
> ---------------------------------------------------
>
> Key: JBREM-1234
> URL: https://jira.jboss.org/browse/JBREM-1234
> Project: JBoss Remoting
> Issue Type: Quality Risk
> Security Level: Public(Everyone can see)
> Affects Versions: 2.5.3 (Flounder)
> Reporter: Ron Sigal
> Assignee: Ron Sigal
> Fix For: 2.5.3.SP1
>
>
> From JBPAPP-4617 "Possible performance issue in Remoting":
> JMS remote connections that are used locally result in a lot of calls to InetAddress.getLocalHost() which for some reason is slow.
> Why not:
> private static final InetAddress LOCAL_HOST;
> static
> {
> try
> {
> LOCAL_HOST = InetAddress.getLocalHost();
> }
> catch (UnknownHostException e)
> {
> throw new ExceptionInInitializerError(e);
> }
> }
> private static InetAddress getLocalHost() throws UnknownHostException
> {
> return LOCAL_HOST;
> }
> Which is roughly 1000x faster.
