Using Tweetily Slows Blog A LOT

Hi,

I love this plugin, I started using it today and it really worked well to bring more visitors from Twitter, but the plugin slows down the server time response a LOT.

I did a big effort to get a good VPS running and I have like 100ms-200ms initial response time, but if I activate the plugin it goes to 1-1.5 SECONDS.

You know why this can be? My website is http://www.productormusical.es
