In our environment, OS cache is much bigger than postgres buffers. Postgres
buffers around 8 GB, OS cache more than 100 GB. Maybe we should inspect

Hello All, I would like to know about how OS cache works for postgres table
and index file.
Let's say I have 10 year data, and commonly used data only the last 1 year.
This data is quite big, so each table and index file is divided into
several file in PGDATA/base
Let's say 1 index named
3 read=30175
Now, index scan on activity_pkey which take much slower. Can someone please
explain these ?
Thanks

Thanks All for the response, finally we figure it out. The slow is due to
high number of dead rows on main table, repack these tables wipe out the
issue.

Hello All
Hello All,
Master db size 1.5 TB
All postgres 9.1.13 installed from RHEL package.
It has streaming replica and slony replica to another servers.
Server performance is slower than usual, before that, there's a big query
got cancelled and then performance get slow.
No sign of IO wait.
on sar,
Changing to a higher rate CPU would be more helpful if you run less than 32
queries at a time.

Hello Everyone ...
We have 6 PG 9.1.12 installation, one master (Ubuntu 10.04), one slony
slave(Ubuntu 10.04), and four streaming replica (2 on Ubuntu 10.04 and 2 on
RHEL 6.5 (Santiago) which lies on different datacenter). All Ubuntu is on
same datacenter. Master send wal archive to slony slave.

Everything works fine until on Thursday we have high load on master, and
after that every streaming replica lag further behind the master. Even on

at all.
