Tried to figure out from firebug and by googling, didn't get any convincing answer.

How many resources will a browser download from a given domain at a time exceptions?

This restriction is defined in the HTTP specification (RFC2616). Most modern browsers allow six connections per domain. Most older browsers allow only two connections per domain.

How many connections Chrome?

Chrome has a limit of 6 connections per host name, and a max of 10 connections. This essentially means that it can handle 6 requests at a time coming from the same host, and will handle 4 more coming from another host at the same time.

IE7 allowed only two concurrent connections per host. But most browsers today allow more than that. IE8 allows 6 concurrent connections, Chrome allows 6, and Firefox allows 8.

So if your web page only has 6 images, for example, then it'd really be pointless to spread your images across multiple subdomains.

It depends on the browser and how it is setup - firefox has controls for how many download threads to use, for example.

The different browsers (and versions) have different defaults as well.
