I love this program, but it slows my site

I love this plugin. It helps our website visitors tremendously to be able to ask questions and interact with us. Many are reluctant to call or email for fear of being inundated with sales calls, so this allows them to stay at arms reach until they get comfortable with us.

Why only 3 stars then? The speed. When I load the Zopim widget, my homepage load time goes from 6.5s to 12.3s. I can’t have visitors waiting that long for our homepage to load. I could live with adding a second or so to our load, but 6 additional seconds is a deal-breaker.
