Sliding down menu is too slow ?

See more:

jQuery

// Set Variables
var search_toggle = 'closed';

jQuery(document).ready(function() {

// Main Menu Drop Down
jQuery('ul#main-menu').superfish({
delay: 600,
animation: {opacity:'show',height:'show'},
speed: 'fast',
autoArrows: true,
dropShadows: false
});

// Accordion
jQuery( ".accordion" ).accordion( { autoHeight: false } );

// Toggle
jQuery( ".toggle > .inner" ).hide();
jQuery(".toggle .title").toggle(function(){
jQuery(this).addClass("active").closest('.toggle').find('.inner').slideDown(200, 'easeOutCirc');
}, function () {
jQuery(this).removeClass("active").closest('.toggle').find('.inner').slideUp(200, 'easeOutCirc');
});
