Fetching all GoogleCalendar Events before FullCalendar has loaded - fullcalendar

Question

I currently am using Adam Shaw's jQuery Calendar 'FullCalendar' and am experiencing significant delays in the calendar rendering. In short, the page appears, 1 second passes, the Calendar pops in, another second passes, and then the events populate the page, here. Is there a way to only fetch a certain number of events behind and before today's date? Or even loading the calendar immediately would be an improvement. I am also using Craig Thompson's qTip2.
Javascript
<script type=text/javascript>
// Setup FullCalendar
jQuery(document).ready
(function() {
var date = new Date();
var d = date.getDate();
var m = date.getMonth();
var y = date.getFullYear();
var tooltip = $('<div/>').qtip({
id: 'fullcalendar',
prerender: true,
content: {
text: ' ',
title: {
},
},
events: {
render: function(event, api) {
var elem = api.elements.bgiframe;
}
},
position: {
my: 'bottom center',
at: 'top center',
target: 'event',
viewport: $(window),
adjust: {
mouse: false,
scroll: true,
method: 'shift',
resize: true
}
},
show: {
modal: {
on: false,
blur: true,
stealfocus: false
}
},
hide: false,
style: 'qtip-bootstrap'
}).qtip('api');
$('#fullcalendar').fullCalendar({
eventSources: ["https://www.google.com/calendar/feeds/emailaddresshere/public/basic",
"http://www.google.com/calendar/feeds/usa__en%40holiday.calendar.google.com/public/basic"],
header: {
left: 'title',
center: '',
right: 'today prev,next'
},
selectable: true,
eventClick: function(data, event, view) {
var content = '<h3>'+data.title+'</h3>' +
'<p><b>Start:</b> '+data.start+'<br />' +
(data.end && '<p><b>End:</b> '+data.end+'</p>' || '');
tooltip.set({
'content.text': content
})
.reposition(event).show(event);
},
dayClick: function() { tooltip.hide() },
eventResizeStart: true,
eventDragStart: false,
viewDisplay: function() { tooltip.hide() }
});
}());
</script>
