Diagnosis
Statistics are recorded for each cache element every time a query isexecuted. This includes the user who created an element by executing thequery, when this was created, the user who changed a query, when thischange was made, the last user who had read access to an entry, whenthis was read, and how often it was read. Writing the statisticsinvolves additional access to the database, which can have an negativeeffect on performance. It is therefore possible to deactivate thestatistics. The standard setting is for this to be activated.
By default, the statistics are buffered and are not written to thedatabase fully until a query navigation step is completed. The systemperformance in this case is considerably better than when data recordsare continuously written to the database. Note the second administrationparameter.
