I'm looking for the difference in performance between those two, I could not found in SSE no good answer about this topic.

Some examples would be of great help.

If you look at the jQuery code you can see that all click() does is execute trigger('click'):

jQuery.each( ("blur focus focusin focusout load resize scroll unload click dblclick " +
"mousedown mouseup mousemove mouseover mouseout mouseenter mouseleave " +
"change select submit keydown keypress keyup error contextmenu").split(" "), function( i, name ) {

// Handle event binding
jQuery.fn[ name ] = function( data, fn ) {
    if ( fn == null ) {
        fn = data;
        data = null;
    }

    return arguments.length > 0 ?
        this.on( name, null, data, fn ) :
        this.trigger( name );
};

Note this: 

    return arguments.length > 0 ?
        this.on( name, null, data, fn ) :
        this.trigger( name );

In other words, "If no arguments are passed to click, execute trigger('click')".

    Might be worth mentioning that this is Standard Operating Procedure in the jQuery source code, or in any decent application for that matter -- if you want the same result, call the same code. The difference in performance between one and the other will always be negligible. – Blazemonger Apr 19 '12 at 14:18
