[opencms-dev] opencms6 - postgresql8 and performance

[Bouchard Sylvie]

Hi,
Please find the script allowing to add the missing indexes in accordance with the MySQL table structure.
We will rewrite the complete script for the creation of the tables for PostgreSQL.
You will receive it as soon as possible.
Thank you very much !
Sylvie

Hi Sylvie,

please keep in mind that the PostgreSQL support has been contributed to the
distribution (the initial version was developed by Antonio Core). The driver
has been reported to work well, but I am not sure about the performance.

Should there be any optimizations, such as the additional indexes you
mention, please contribute these back to the OpenCms community so that we
can include these improvements in a futire distribution. 

Best Regards,
Alex.

> Good afternoon,
> We have an application based on opencms6 / Tomcat5. The data

> The pages' display is very slow (it can take up to several

> - Bi-processor Intel Xeon 3.0 GHz
> - RAM 4 Go
> - Disks on SAN - access through optical fibre

> I have noticed that several sequential accesses happen on the 
> tables of the cms during the questioning.
> We added the same index as those in scripts of MySQL. The 
> access method and times are better but still too slow

> My questions :
> What would be the best configuration parameters of the 
> postgresql.conf file (or another file) to enhance the performances ?
> What could we do on Opencms' side to improve the data interrogation?
> Is the creation of the tables (index) through opencms optimum ?
> Your advices are most welcome.
