NMC GUI slowness

Hello,

I am running networker version of 19.6. Sometimes i see the GUI interface is very slow and when we restart the GST, networker service from storage node and networker server it becomes better. I tried looking if this could be problem because of JAVA heap size but already gave a good size of 512Mx.

Is there anything need to be analyzed to look for the reason behind the slowness of the GUI. The slowness is even there when there are no scheduled batches running in the system.

We are running the networkers in LINUX OS.

Please shed some light on the above on what needs to be looked further to fix this.
