Hello all,
 Could i get a help, postgres 1 billion records indexed table, search speed in a normal machine, no parallel processing ... for a knowledge ??

1. How big are the records?
2. How big are the keys?
3. What is a normal machine?
4. Why no parallel processing?

Anyway... off the cuff, for 1 giga-rows, that's about a 50GB table.  Small enough that you can easily test that yourself.

Hello,
1 field 20 chars plus primary key id field - small table
indexed on that char - 20 field , say 16 gb ram, amd normal power processor
no parallel processing, to know it, the speed in single processor

Ok?

Honestly, your questions puzzle me: PG is open source, binaries are available for Windows, every Linux distro, and even BSD.  And the database is pretty small.

Install it, and test it yourself.

Then you'll have the answer.

Hi,
I mean any manual
 I have a small code, that searches some 10000 billion records in 1 seconds thru index simple case -- I want to test that with postgres
