        Marketing statistics considerations
        Operational marketing statistics are gathered and stored in the database by the RaiseECEvent scheduled job that is run by the Scheduler at a set interval. You can modify its scheduling parameters to decrease or increase its run timing and constraints. This allows you the ability to finely control its throughput and its associated impact on site performance.
        Web activities performance
        For Web activities, HCL Commerce attempts to store the information that is required for your activities in memory or in a cache. This information is then used to determine what to display in e-Marketing Spots. This marketing design reduces the complexity and invalidation that is required when JSP caching an e-Marketing Spot.
        Improving Email activity sending performance
        You can set two parameters in the EMLMSG database table that can improve performance when you use Email or Dialog activities to send marketing emails.
        Tuning the marketing business object cache
        You can improve performance by altering the size of the cache that is used to store marketing business objects. You can cache the marketing business objects for a store and cache the information for customers that participate in marketing activities.

Avoid extra Ajax call from V9 Remote store

A number of remote stores make an Ajax call to register marketing events. This call, AjaxRESTMarketingTriggerProcessServiceEvaluate, can be sent from store pages, including category navigation pages, product or item display pages, or search result pages. You can disable this call if you have no need for it.

To disable the AjaxRESTMarketingTriggerProcessServiceEvaluate call for your remote stores, issue the following SQL command.

insert into storeconf values ($storeId ,'wc.store.unregisterMarketingEvent','1',0);

If wc.store.unregisterMarketingEvent=1, then remote store pages will not register marketing events with the Transaction server. It follows that any marketing features that rely on these events will not work. For example, the display of recently viewed products will not occur if it is triggered by this Ajax call.

Note:

The insert command addresses one store, by means of its $storeId. You will need to run the command separately for each remote store whose Ajax call you want to disable.
The parameter wc.store.unregisterMarketingEvent is case sensitive.
