Finally, the problem is narrowed down to the response time of rowCount() from
back-end.
I commented out the database call in Rpc back-end and put a hard-coded value
of 15000 for rowCount().
Now, it is 100 times much faster.
What piece of code in the Remote Table is triggering rowCount() indefinite
times, when the rpc timeout 30 secs is specified?. In my case I get
rowCount() in 5 secs < 30 secs. What is the use of Rpc Timeout?
Can somebody explain this please?
Thanks.
