[opencms-dev] Performance issues with detail page

[Àlex Rodríguez Bacardit]

Good morning,

 

We’re currently testing the performance of OpenCms by load testing the
different page types. By testing them one at a time, we’ve found that the
detail page suffers greatly when accessing it with more than 50 users.

Our last test included 50 users accessing concurrently to a detail page, and
the response times are far higher than the rest of the pages. For your
information, we’re testing the detail page of the default site.

 

Analysing the thread dumps we can see calls to synchronized methods such as
isDetailPage and getParentFolderType, both coming from the
CmsConfigurationCache class. What does this class do, we can not yet tell,
and thus we’d like to know where is this CmsConfigurationCache class called
from.

 

These calls to synchronized methods generate response times way too high,
either because the locks aren’t released correctly or because there are
deadlocks within the calls. 

 

What is this cache exactly? Can it be disabled? Is it part of flexcache or
can we find more documentation on this class?

 

Best regards,
