Dear all,

I have implemented a number of slow control frontends which are directed to update the 
history once in every 10 sec, and they do just that. 

I expected that such frontends would be spending most of the time sleeping and waking up 
once in ten seconds to call their respective drivers and send the data to the server. 

However I observe that each frontend process consumes almost 100% of a single core CPU time 
and the frontend driver is called many times per second. 

Is that the expected behavior ?

So far, I couldn't find the place in the system part of the frontend code (is that the right 
place to look for?) which regulates the frequency of the frontend driver calls, so I'd greatly 
appreciate if someone could point me to that place.

I'm using the following commit:

commit 30a03c4c develop origin/develop Make sure line numbers and sequence lines are aligned.

-- many thanks, regards, Pasha
