ultimate facebook causes backend to stall on load

WP 3.3
Ultimate Facebook 1.6.1
only ultimate facebook plugin installed
latest firefox - just cleared cache

When I visit anything associated with wp-admin, ultimate facebook causes a stall of about 20 seconds before the wp-admin loads. I tested with my plugins loaded minus facebook, it takes about 3 seconds to load, with UF, about 20. I disable UF, load time is back to about 3 second. I disable all plugins, activate only UF, 20 second load time. I really only want to use this for the like send buttons. Iv attached the settings im using, everything else is default or not activated
