| Largest response time | The largest response time in milliseconds for all page requests across the entire web site. To view the response time for individual pages, see the Page response time tabResponse Time. |
| Largest query execution time | The largest query execution time is the execution time of the longest of all SQL queries performed on all databases. To view the query execution time for individual queries, see the Queries tab. |
| Largest response time Page Generator | The largest response time in milliseconds the Page Generator took to fulfill a request. To view the Page Generator response time for individual pages, see the Page response time tab. |
| Average response time Page Generator | The average response time in milliseconds that the Page Generator took to fulfill requests. To view the Page Generator response time for individual pages, see the Page response time tab. |
| Average response time | The average response time in milliseconds for all page requests.To view the response time for individual pages, see the Page response time tab. |

The Page response tab shows a list of the slowest page response times in milliseconds for pages requested from the website. The page response tab lists two different types of pages:

The level at which you log messages has a direct effect on system performance. Each time a system event is logged, a small performance hit occurs. Logging messages of type SEVERE affects the system the least whereas logging at the INFO level can cause the system to slow down due to the sheer volume of messages that are written to the log. The effect that the logging level has on XperienCentral performance is indicated as follows.

To change the log level, follow these steps:
- Open the
<tomcat root>\conf\logging.propertiesfile. - At the end of the file, the following lines should appear. If they do not, add them.
org.apache.jackrabbit.core.level = <level>org.apache.jackrabbit.core.state.level = <level>nl.gx.XperienCentral.level = <level>org.apache.jackrabbit.level = <level>org.quartz.level = <level>org.springframework.level = <level>- Substitute
<level>with the level at which you want to log (SEVERE,WARNING, orINFO). Logging at the levelSEVEREis recommended.
