Optimize sessions require intensive processing. There are several configuration properties you can use to tune this processing. However, these configuration settings are for your entire Optimize installation. Based on the campaigns included in an Optimize session and your optimization rules, the ideal settings for one Optimize session may not be as optimal for another Optimize session.

You can use advanced settings in each Optimize session to set values for the configuration properties at the session level. These settings work the same as the configuration properties, except that they are applied for the particular Optimize session. For example, you can set CustomerSampleSize to 1000 for one Optimize session and 1500 for another Optimize session.

To apply advanced settings, select Use custom session settings in the Optimize session properties. After selecting the Use custom session settings checkbox, you can define values for the Optimize session. If you are defining your Algorithm Tuning and Logging settings in your Optimize session, all the session properties override the installation-level settings in your configuration properties.

To edit the advanced settings, expand the Advanced Settings section of the Optimize session and click Edit Advanced Settings. You can also click Edit Session Properties on the Optimize session summary page.
