what is Sanitization.SanitizeHtml slow extension?

In the Monitoring > General Log section, i saw a list of Sanitization.SanitizeHtml. How can I resolve this issue?

Solution

You cannot, and you need not. It logs everything that takes more than 0.2 seconds or the like. Unless it really takes seconds, there's no need to do anything.

Solution

Is there anyway for me to change the setting to log only those that takes more than 1 second instead of 0.2 seconds?

Unfortunately not, as far as I'm aware. You can however completely turn off the logging, in Service Center, "Operation" tab for the eSpace ("Activity Logging").
