How can I get my site to load faster

[Zacdaniel]

I seem to notice that my website seems to have moments of long load time.
Would there be any reason for this or is it normal for it to delay some loads?
Some times it would load instantly and on other loads it can take up to a minute to load what's essentially an empty site at this stage?

if it hangs, it maybe your server, not saying it is, just that it might be.
OSCLASS is pretty quick out of the box

fksockopen make an DNS-Request for each file it load. To change the Domainname with localhost-ip (127.0.0.1) make it significant faster for me!

Rethus I have changed $host to 127.0.0.1 but this error appeared on the top of the page:

Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /home/username/public_html/oc-includes/osclass/utils.php:1) in /home/username/public_html/oc-includes/osclass/core/Session.php on line 47

Or I need to change $host to pages IP?  I am bit worried about making changes, because my site is already running...
