This definitively doesn't look like something that has to do with postgres settings, can you show us the statement and the explain plan ?
Also , have you checked pg_stat_activity to monitor what is running at the same time when the delay occurs ?
It kinda looks like a lock to me.

Hi all,
Currently, I'm working on a performance issue with a query which takes
around ~30 sec to complete. This happens only, when there are more
activity going around same table. The same query completes with in a
second when there are no activity on that table.
Tried taking EXPLAIN ANALYZE output and analyze it, since it completes
with in a second, there are no blockers in it.
Is there any way to see whether postgress settings creates the
problem? which could be related to memory, locks or I/O etc..
Thanks for your help.
