QuadEM Update rate limited by lock

[Iain Marcuson via Tech-talk <tech-talk at aps.anl.gov>]

I am writing EPICS for a QuadEM, based on designs in the distribution.  The data come at 200 Hz, and my benchmarking in EPICS shows that I receive at that rate with very low jitter.  Following the examples of other electrometers, I lock() before computePositions() and callParamCallbacks().  I have observed that the lock() takes about 6 ms, which is too long for the full packet rate.  Is this a normal time for the lock()?  I believe I have eliminated other calls for the lock() in my code, although a calltree shows lock()s in the callbacks.

 

Thank you,

 

Iain.
