How to tell google syndication not to wait forever to load the ads in case of slow internet connection or otherwise too? Can we fix a time that says okay go and search for 5ms to get ads otherwise don’t delay the load of rest of page.
The YSlow extension for Firebug is great for this sort of thing, it benchmarks your page loading and tells you what's slow, and advises what techniques you can use to improve things.
For example, it gives you advice on where to put your javascript to aid the speed of your site as perceived by the user.
