Thread: [Postgres-xc-developers] Where is the benchmark?

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 422-6466

Hi! guys
   I want studying Postgres-XC v1.2 for new project. I
   Where is the benchmark testing of Postgres-XC? I saw a old benchmark 
in Website, I can't find it now.

-worm

Scalability result for DBT-1 will be found at https://sourceforge.net/apps/mediawiki/postgres-xc/index.php?title=Scalability
which is linked from the main page of Postgres-XC Wiki, https://sourceforge.net/apps/mediawiki/postgres-xc/index.php?title=Main_Page

Pgbench result has been published at https://www.pgecons.org/wp-content/uploads/2014/pgecons2013png/wg1_scale-out.png
Sorry, it is in Japanese.

Regards;

Title: comparison 2012/2013

Up graph: read load
Down graph: write load
The rest can be guessed.

As much as I heard, their benchmark in 2012 was not correct.   I had some talk with PGECons people and they made several correction on it.

Btw, it is hard to give to those tests much value without more details about:
- The hardware used. How many CPUs? How much memory?
- The settings of server, like postgresql.conf. How many shared
buffers? Was catalog and/or pgbench data cached? pre-warmed perhaps?
- Structure of the cluster (1Co/1Da per server, all at the same place?)

Why the perf result of PostgreSQL decreased from 2084 to 910 at  2012 to 
2013 at the Pgbench results?
and Why the 4XCnode is much more than 4 times faster than 1 PostgreSQL?

You can find answers in this report.
 * https://www.pgecons.org/downloads/43
While this is also written in Japanese, you can apply a machine
translator. You can copy and paste all sentences including texts in
the figure.

Rough summary of their considerations is...
 * Why the perf result of PostgreSQL decreased -> they had much
memories and high-performance CPU in 2012 compared to 2013.
 * Why the 4XCnode is much more than 4 times faster -> 4X cache
memories (sum of cache memory in all data nodes) gave such
improvement.
