Increase the "gateway.timeout" value to allow longer processing time for complex visualizations Increasing the "gateway.timeout" value allows more time for the server to process complex visualizations without timing out, which is essential for a company focusing on de-tailed and complex data visualizations. Option B is incorrect as decreasing session expiry timeout may interrupt the visualization process. Option C is incorrect because limiting extracts refresh frequency does not directly impact the processing time of complex visualizations. Option D is incorrect as decreasing data server timeout might result in insufficient time for data retrieval, especially for complex queries.
