[jira] [Created] (ISIS-2031) Using 'show all' on tables does take longer than expected

[Andi Huber (JIRA)]

Andi Huber created ISIS-2031:
--------------------------------

Summary: Using 'show all' on tables does take longer than expected
Key: ISIS-2031
URL: https://issues.apache.org/jira/browse/ISIS-2031
Project: Isis
Issue Type: Bug
Components: Core: Viewer: Wicket
Reporter: Andi Huber
Assignee: Andi Huber
Fix For: 2.0.0-M2


When fetching and displaying 25 objects (rendering a table) takes 1s, then the same with 100 objects should take about 4s, but it takes way longer.

This is strange. I also noticed, that after having fetched all objects from the DB, the viewer is still occupied with rendering, showing the long-running indicator.

This needs some investigation.

Andi Huber commented on ISIS-2031:
----------------------------------

Just learned, that I'm only seeing this on my development environment with prototyping mode. Production is fine, but production is also way faster.

In addition to 'show all' being slow, also switching between paged-table pages (Ajax navigation bar, at the bottom of tables) is incredibly slow!
eg. first page 25 objects loads in 0.3 s. Then navigating to the second page takes 17s.

Clearly there's something wrong.

Andi Huber commented on ISIS-2031:
----------------------------------

Symptoms go away with disabling L1 cache verification:

isis.persistor.datanucleus.impl.datanucleus.findObject.validateWhenCached=false

From DN's webpage:
When you call the method getObjectById if an object with that identity is found in the cache then a call is, by default, made to validate it still exists. You can avoid this call to the datastore by setting the persistence property datanucleus.findObject.validateWhenCached to false.

WE need to further investigate, whether we can optimize this on our side, without disabling L1 cache verification.
