Google Plus One Performance

Thanks for the link, I'm concerned about JavaScript performance too.
Notice that I'm placing the script by default in the footer, so it shouldn't block rendering the HTML.

I will read further about it later, but the script he puts in the bottom looks nice.

I knew these other lazy loading patterns http://friendlybit.com/js/lazy-loading-asyncronous-javascript/
but each technique seems to have different issues or incompatibilities with browsers.

Other option is to cache the js file (like google analytics module does) so it can go through the normal js aggregation / gzip it and not as external script. Plus if you have LabJS, HeadJS, etc type modules... they will be able to optimize it.

But as I said, once I finish stabilizing the modules, I will look further into it.

Postponed by now, at least some days. Thx

I added an option for 7.x dev branch to download Javascript asynchronously

I will appreciate feedback about it before made a release, specially because will be the default option.

Looks like Google might have just saved you some work.

thanks andy, I saw it some hours ago.
I'm using almost same snippet already for some weeks, but now that is official is much better. Soon after holidays I will update the module.

The good news is that they are now rendering the button much faster, before was taking 2 seconds.

closing this. it was fixed long time ago
