are there amendments to the standards iframe code generated with the widget that will allow the iframe to load faster on the webpage?

I use wordpress for blogs and on accessing the websites Blog page where there is an iframe generated with the web designer widget, there is a lag which is annoying. it does make some kind of sense that there will be lag when another website/page is loaded, after all your website must load before it sees there is an instruction to load another site in an iframe.

But can the load time be increased in some way.

Not great with code and hoping there is an easy solution ............ thanks in advance for any help

Current code:
<iframe src="http://www.domainname/blog/" onload=”pageloadingtime();” width="100%" height="100%" frameborder="0" scrolling="auto" name="xara_iframe" ><p>Your browser does not support iframes.</p></iframe>
