We are using free version of wordfence for now and planning to go premium as soon as our wp website get completed, I noticed that our outsourcing developers are working fast but we are getting serious optimization issues with following wordfence script which is appearing in main and all inner-pages of website.

Found JavaScript inside head
<script type=”text/javascript”>
(function(url){
if(/(?:Chrome\/26\.0\.1410\.63 Safari\/537\.31|WordfenceTestMonBot)/.test(navigator.userAgent)){ return; }
var addEvent = function(evt, handler) {
if (window.addEventListener) {
document.addEventListener(evt, handler, false);
} else if (window.attachEvent) {
document.attachEvent(‘on’ + evt, handler);
}
};
var removeEvent = function(evt, handler) {
if (window.removeEventListener) {
document.removeEventListener(evt, handler, false);
} else if (window.detachEvent) {
document.detachEvent(‘on’ + evt, handler);
}
};
var evts = ‘contextmenu dblclick drag dragend dragenter dragleave dragover dragstart drop keydown keypress keyup mousedown mousemove mouseout mouseover mouseup mousewheel scroll’.split(‘ ‘);
var logHuman = function() {
var wfscr = document.createElement(‘script’);
wfscr.type = ‘text/javascript’;
wfscr.async = true;
wfscr.src = url + ‘&r=’ + Math.random();
(document.getElementsByTagName(‘head’)[0]||document.getElementsByTagName(‘body’)[0]).appendChild(wfscr);
for (var i = 0; i < evts.length; i++) {
removeEvent(evts[i], logHuman);
}
};
for (var i = 0; i < evts.length; i++) {
addEvent(evts[i], logHuman);
}
})(‘//demo-octalogo.com/iworldteam/?wordfence_logHuman=1&hid=1427550101F48143BEA564C41AB6CA1F’);
</script>

I read in previous post that is for live traffic monitoring, but why it is automatically appearing in head of site, where all optimization testing website is marking it as error and not good for placement. Also our hosting provider, where we have just 25 processes available is indicating that these javascripts in head might be the reason of “extra processes” consumption on our hosting account, due to which we are running out of server resources fast, please check the aforementioned script and enlighten us with your professional point-of-view, thank you.
