Hi,

I was running a project with a table components SQL query binding with polling on. At a time, at least 5 clients will be logged in.

Now I changed to polling off and using a system.util.sendmessage to refresh binding in all clients and I found the memory usage has reduced.  
CPU trend has gone down from average 20% to 10%

I still find memory heap is 2.5 GB. Previously it used to 3.3 GB.

Is this normal?
