@AnilKumarRaj  please can we ask that you do not post identical questions twice on this forum?  Duplicate posts cause unnecessary admin work and confusion when answers get lost.

You asked the same question in the post Chatbot in portal and bot response is very slow

This is also not a valid 'Discussion', which we reserve for developer knowledge shares and product news and events.  I will therefore close this discussion in favour of your open question found here.
