Dear All,
we are facing some problems using the viewer Ds from Lima, in particular some speed problems.
How could we improve the live video speed ? From Tango side we played with events / polling but no changes in the camera video acq rate ....
Thanks

Hi Hayg,
I think you are facing with performance issue of the limaviewer server which download the raw image from the LimaCCDs server then reshape (numpy) the data. Could you profile the how much time reading the attribute Image_ccd takes?
Is your limaviewer running on the same computer where LimaCCDs is running?
Why not to only use LimaCCDs and read the image from it?
