Sending mail takes 2 seconds

Question

When I use this code, it takes 2 seconds to execute.
It is a static method and code is run on my tomcat server.
It all works fine, just the length of time to execute.
Questions:
Why is this taking 2 seconds, any way to speed it up ?
Should I just stick it in a separate thread and let it work on it's own so users don't have the delay ?
Thanks
public static void doIt(String to, String subject, String text) {
        try {
            Context initCtx = new InitialContext();
            Context envCtx = (Context) initCtx.lookup("java:comp/env");
            Session session = (Session) envCtx.lookup("mail/Session");
            Message message = new MimeMessage(session);
            message.setFrom(new InternetAddress("[email protected]"));
            InternetAddress list[] = new InternetAddress[1];
            list[0] = new InternetAddress(to);
            message.setRecipients(Message.RecipientType.TO, list);
            message.setSubject(subject);
            message.setContent(text, "text/plain");
            Transport.send(message);          
        catch(Exception e){

Answer 1

Obviously you should do some debugging to determine which statement is using most of the time.
Most likely it's the call to Transport.send, but you should prove that.
Since Transport.send is talking to your server, the delay could be entirely waiting for your server.
Also, Transport.send will need to look up the host name that you're connecting to. If your name
service is slow, that could explain it too.
