I am glad to have found Wordfence and installed the free version. However, I noticed that after I installed wordfence to my site it adds at least 4 to 5 seconds of delay.
I used pingdomtools to measure the incremental load time. This is the site in question - http://cosmeticsurgeonnewportbeachca.com
4 or 5 seconds of delay may not sound much but it will piss off a lot of visitors to my site and this will increase the bounce rate and abandon rate.
Can you please look into it and advise what needs to happen to reduce wordfence load time.
