[opencms-dev] Performance Patch for Opencms

[Brabenetz, Harald]

Hi,

we created a performance-Patch for the Class CmsXmlEntityResolver.java

The CmsXmlEntityResolver clears his cache on every publish event, even if no "schema-definition" where published.
Also the LRU Cache has low dimensions (128 row-File-Content Entries and 64 parsed Schema-Definition Entries for the whole online and offline project).

* We made the following changes:
   1. The Cache will only be cleared on publish-event if a Schema definition (*.xsd or *.dtd) where found in the publish-List.
   2. The LRU-Cache were increased:
      o 1024 entries of row-File-Content (Map m_cacheTemporary)
      o 512 entries of already parsed Schema Defintion Objects (Map m_cacheContentDefinitions)

The Patch is attached (Works at least for OpenCms 7.5.2 and 7.5.3)

With friendly regards,
Harald Brabenetz
