|
<p>To optimize page generation time, Piwigo uses cached
|
|
information. For example, instead of counting the number of photos
|
|
contained in each album at each page reload, this information is stored
|
|
in the database. In theory, this information should always be correct, but
|
|
sometimes an error can occur and cached information becomes wrong.</p>
|
|
|
|
<p>Some information become useless with time going by. Deleting this useless
|
|
information from database make you save disk space.</p>
