Temperature polling Version 1.3.7

What is the problem?
Temperature updates seem to be very slow and printer seems sluggish to respond to needed adjustments in temperature than in earlier versions of octoprint.

What did you already try to solve it?
Reduced polling intervals for temperatures to 1 sec. Still appears to be updating every 5 seconds.

Additional information about your setup (OctoPrint version, OctoPi version, printer, firmware, octoprint.log, serial.log or output on terminal tab, ...)
Octopi: Version 1.3.7
Wanhao i3

Just downgraded to 1.3.6 problem seems resolved.
