MQTT Ciao performance

Dear guys
I find very little examples of Ciao library usage for MQTT.
Do you have any idea about the performance of this library?
More specifically, if I try (on a Yún) to update a parameter of my main loop using Ciao.read("mqtt") from a broker on a computer from my local network, how long will this Ciao.read last (since it will decide the period of my loop)?
Thanks in advance for your input!
All the best
Mat

The Ciao library was some attempt at cuteness from Arduino.org. You should ask them your questions.

I thought that the "org vs cc" story was over (Two Arduinos become one | Arduino Blog)

How shall I ask "org" my question?

Thanks!

Apparently, they've kissed and made up, since the .org site now redirects here. I do hope some of the malcontents that broke away, and have now come back, come here to answer these kind of questions, about products and hardware that they released, that are no longer supported.

As far as I know the yún is still supported... and the Ciao library is also compatible with the Tian.

Anyway I can expand a little bit my question:
What is the best library (in terms of performance ~= fast read/write) to read/write data from/to a MQTT broker?

No one uses MQTT??
Thanks!!
