Feed takes up to 5 minutes to post new updates

Hi,

I’m using dlvr.it to automatically posts RSS feeds to social media. According to the article mentioned below the feeds should publish in real time, but it takes up to 5 minutes:

Is it possible to publish feeds on social media in real time without the latency of 5 minutes?
