Subject: poll_event() is very slow.  
Something must be wrong on your side. If you take the example frontend under

midas/examples/experiment/frontend.cxx

and let it run to produce dummy events, you get about 90 Hz. This is because we have a

  ss_sleep(10);

in the read_trigger_event() routine to throttle things down. If you remove that sleep, 
you get an event rate of about 500'000 Hz. So the framework is really quick.

Probably your routine which looks for a 'lam' takes really long and should be fixed.
