Memory Flush

Hi,

Is there any option to flush the memory at a regular interval via a cronjob?. This is currently available in the GUI, but that requires user action. Please suggest.

Thanks

HI Joby,

there is no need for this, as the Java virtual machine automatically takes care of this.

The manual flush option is there to determine the current memory footprint.

Hi Torsten,

Can you suggest any method to speedup klaros. Currently our klaros site running very slow on an amazon medium instance.

Thanks

Hi Joby,

two points come to mind here:

  • Make sure that you have allocated enough memory
    The default memory settings used during installation may be a bit to small if you are using lots of user sessions or large databases.
    Trying to raise the default heap memory from 512MB to e.g. 768MB can help performance tremendously.
  • Avoid using large page size settings in tables
    The current implementation does not perform well when rendering large table page sizes (like 50 or more). This is a known issue which will be fixed in the 4.2. release. In the meantime, please try to keep these settings low, rendering speed scales with this settings currently.


If this does not help, please send the output of http://<klaros-server:<klaros-port>/klaros-web/monitoring?format=pdf to support@verit.de so we may have a closer look at things. The credentials asked to access this page are the ones you entered for the tomcat administrator during installation. They can also be found in the file conf/tomcat-users.xml in your Klaros installation directory.

Hope this helps,

Torsten

Hi Torsten,

Thanks for the suggestions. I will try this and let you know the outcome.
