Subject: Question about the speed of synchronization of CaChannel ?

Hi,


I use CaChannel python package to monitor a PV 'caLab:okok' and do some simple treatments of the PV value, then synchronise the treated PV value to 'MTEST:d00' and 'MTEST:d01' , and it works.


However, the problem is that when monitoring the PVs ('MTEST:d00' and 'MTEST:d01'), the  speed of synchronization of "camonitor MTEST:d00", "camonitor MTEST:d01" are quite slower than "camonitor caLab:okok", and  MTEST:d00 and MTEST:d01 lost many data from caLab:okok.

I have no idea how to solve the problem, I try to modify the command "server.process(0.1)" to "server.process(0)" of the main function, but  I failed, the speed of synchronizaiton is still very very slow, and it seems the more PVs synchronization the slower the speed is.

Any help will be appreicated and thanks in advance !
