Re: CSS performance

[Benoit <benpaka.spam@gmail.com>]

Hi Kunal,

I am using v3.2.16 but I am not "authorized" to change the version so easily. Anyway I will try to install v4.x just to see if we don't have anymore these freezes.

I will also try to add more VM RAM and told you if my problems appear again!

I am using Python script instead of JS (more used to write python code), do they consume more CPU/RAM?

Then do you know a way to get the script usage (CPU/RAM) to see if I have one script more thirsty than the others because they are actually quite simple.

Regards,

Hello Marcio and Benoit,

 

What version of cs-studio are you using?

Also could you give provide some details about the opi screens which result in the freeze. Are there any scripts or rules associated with those screens.

 

With cs-studio 3.2.x and 3.3.x make sure you have allocated enough perm memory (especially if you are using a lot of scripts)
You can set it with the following VM argument in your config.ini file -XX:MaxPermSize=256M

 

With the 4.1.x (latest release), cs-studio moved to a newer version of pvmanager with improvements intended to reduce cpu and memory load

You could try one of the 4.1.x products and see if that resolves your problems

Hi Marcio,

 

I have also similar bottlenecks and screen freezes when using CSS/BOY under windows 7. Never saw these problems with ubuntu 14.04.

In my case the problem seems to come from RAM usage: at some point the RAM consumption is going really high and then CSS/BOY freezes.

 

If someone has some suggestions it would be nice.

 

Cheers,
