[Achim Westermann]

Hi Harald, 

maybe this is a candidate for an bugzilla entry along with the patch and a good explanation. Just to make sure that this is not forgotten in future releases. 

kind regards, 

Achim

> 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)
