This view allows you to view Zope database cache statistics and set cache parameters. The Zope database cache operates by keeping recently used objects in memory to improve performance. A large cache improves object access speed, but increases memory usage. A small cache reduces memory usage but may slow down object access speed.
Total number of objects in the database
Total number of objects in memory from all caches
Target number of objects in memory per cache
This parameter is one factor affecting the amount of memory
use by Zope. It controls the amount of memory used per cache,
the other factor is the number of caches. In general,
Zope uses one cache per worker thread (specified by the
switch on the command line)
Total number of objects in each cache
Number of objects in memory
Note that the total number at the bottom of this column should be the same as the figure in the top half of the page. It may be slightly different because there is a small time interval between the calculation of the two totals.
Number of ghost objects
