I've read the first link but not the second link. Your hardware could be undersized, but it is
hard to say without knowing the actual number of concurrent connections. Also, what exactly are
you experiencing when you say that your server is not able to keep up? What does a vmstat 1 10
show while you are experiencing slow preformance. Do you have sufficently aggressive autovaccum
setting? Also, have you adjusted any of your postgresql.conf parameters?
