Avoid excessive calls to InetAddress.getLocalHost() [Clone of JBREM-1234]
-------------------------------------------------------------------------
Key: JBREM-1235
URL:
https://jira.jboss.org/browse/JBREM-1235
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.
