Aspects of the present invention disclose a method, computer program product, and system for query execution in a multi-tenant cloud service. The method includes one or more processors determining category classes for service queries. The method further includes sending for execution, a selected number of service queries from one of the determined category classes to a shadow query engine. Respective service queries of the categorically classified service queries comprise a different set of configuration parameter values for the shadow query engine. The method further includes recording metadata for the selected number of service queries of the one category class executed on said shadow query engine. The method further includes determining correlations between the recorded metadata. The method further includes determining, from the determined correlations, optimal configuration parameter values comprising optimal configuration parameters for executing the selected number of service queries of the one category classes.

A computer-implemented method for reducing cookie traffic in browser communication is provided. The method sends, by a browser to a domain, a first request resulting in a returned cookie. The returned cookie includes a category tag. The method adds the returned cookie to a set of cookies for the browser. The category tag of the returned cookie is added to a related category tag in a browser tag list. The method sends, by the browser to a server of the domain, a second request resulting in a returned list of required category tags. The method sends a selected cookie with a category tag relating to at least one required category tag of the list of required category tags for the server. The selected cookie is selected from the set of cookies and the category tag for the selected cookie occurs within the browser tag list.
