Debug Messages

The above sketch was minimized and all crap not needed was removed. What I actually do is to measure some values via I2C bus and build a message, that is being sent to the server. As the server gets messages from several nodes it calculates a timespan and tells the sender of a post, how long to sleep before the receiver should wake up and transmit some new values - but this is unrelevant.

As you can see, I have set a timeout of 200 ms - You can change the value but what happens is the following (self created) debug output. It will transmit the data, and will get the message from the server

[HTTP   ] POST... code: 200
[HTTP   ] POST... code was O.K 
12345 //<this is the value my server sends me ...
[HTTP   ] total duration of http-PUT: 973 ms.

Basically: there seems to be an uninfluencable timout of 5000ms that I can not change.
What am I doing wrong?

I think, that http.setTimeout(...) is only implemented for ead data. Not for connect and write.
