Database log in

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 

All,

I am experiencing intermitently, slow, log in times.  My connection scenario:

  1. Kube pod is hosted in Ohio, in AWS account A.
  2. Using psql, a log in attempt is initiated from the pod.
  3. RDS Postgres Instance is hosted in Ohio, in account B.    host has 8 vCPU and 32 GB of RAM.  CPU and IO are not a bottle neck.
  4. We experience intermittent log in slowness. 

My questions are around what happens at log in time; what are the sequence of events?  Also, how much “stress” does log in have to the DBMS?  How many concurrent logins can the DBMS handle in a short time frame?  Can 40 sessions be initiated within 90 seconds?  60 seconds?

Please, I would appreciate debugging suggestions.

Thank you in advance, Kim.
