Folks, here comes an important update!

In v1.5-0 cpu load is being reduced by about 90%. In prior versions the routines for checking server status and number of connections generated a cpu load of 6% (measured with top in ssh). The reason was to be found in the python command
which in python 2.5 does neither allow direct piping beween shell commands nor writing directly into a variable. I replaced it with the legacy command
which reduced the respective code to two lines and the cpu load to 1,7%.

In addition I increased the tracking interval of 2 seconds to finally 5 seconds, which feels still reasonable to me. It led to further decrease in cpu load to 0.6%.

Another option has also been added (as a result of discovering the former cpu load ):

• Stop server when not connected for xx minutes

...still a suitable option, even with heavily decreased cpu load.

Finally I added setting signal strength to high level when keeping off wifi power management.


Changes in v1.5-0:
*cpu usage reduced by 90% (from about 6% to 0.6%)
*new option: Stop server when not connected for xx minutes
*signal strength set to high when wifi pm is off
