Experimental Physics and
Industrial Control System

Hi,

 

We have a client application that saves, compares and restores machine values. As part of the compare feature it maintains channel access monitors to the desired PVs .  As the number of requested PVs increased, the performance slowed down (somewhere > 2000 PVs it became noticeable). Do other people have applications that maintain 1000’s of monitors without slowdown ?

 

This is a Java app, that uses JCA 2.1.5  for channel access, and displays results in JTables. I’m wondering if the problem is in the design choice of using monitors, or something else.

 

Thanks,  John G
