[jQuery] selector speedup

[Bruno K]

Hi all

I profiled my script with firebug and have seen that the "filter()"
function is called very often.

As far as I see this function is called when i use a selector like
$("table[name="+name+"]")...

Is there a possibility to speed that up?
In XSLT there is the "key" function.
see:
http://www.w3schools.com/xsl/func_key.asp
It's used to make XPATH queries fast.

Is there a function like xslt:key for selectors in Jquery?

thanks

Bernhard
