CPU Usage

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

 



Postgres 8.1

Linux Redhat AS 4.X

4 processor box

We have 12+ schemas in 1 database. When I do a unix “top” command I notice one postmaster process has 100% CPU usage.  This process just stays at 100% to 99% CPU usage.  There are other postmaster processes that pop up.  They use hardly no CPU or memory.  They also disappear very fast.  I am wondering, is postgres only using one processor for database queries?  Is there something I need to do to tell postgres to use more than one processor?  Or does postgres only use up to one processor for any particular database? 

 

Thanks for your help,
