When performance logging is enabled, Movable Type will attempt to log as much information as it can during the life-cycle of a request. Doing so will provide valuable information regarding specific areas of the application that could benefit from performance tuning, and will allow users to more easily analyze what within their system may be contributing to poor performance.

Movable Type will attempt to log:

• Information about your operating system, installed software, etc. (this information is logged only once)
• How much memory is being utilized by the process at the beginning and at the end of the request.
• How long it takes to process each template tag, both within the application and on the published blog.
• The URL of the request
• The process ID of the request for easier correlation and log analysis.
