# Pentaho Reporting performance tips

Pentaho Reporting's default configuration makes certain assumptions about system resources and the size, features, and details of reports that may not meet your specific requirements. If you have large inline subreports, or many parameters, you can run into performance bottlenecks. Fortunately, many performance problems can be mitigated through specific engine and report options. Refer to the sections below that apply to your scenario.
