Re: database slowdown while a lot of inserts occur

I forgot to mention that the slowdown in particular for other applications is when they are trying to insert or update tables unrelated to the application mentioned in my prior application that does the massive small inserts.

Subject: [PERFORM] database slowdown while a lot of inserts occur

PostgreSQL 9.0.x
We have around ten different applications that use the same database. When one particular application is active it does an enormous number of inserts. Each insert is very small. During this time the database seems to slow down in general. The application in question is inserting into a particular table that is not used by the other applications.

1) What should I do to confirm that the database is the issue and not the applications?

2) How can I identify where the bottle neck is occurring if the issue happens to be with the database?

I have been using PostgreSQL for eight years. It is an amazing database.
