Some webscripts are declared "readwrite" but should be declared "readonly" if they do not update the repository.

Some wescripts are declared <transaction allow="readwrite"...> but should be declared <transaction allow="readonly" > if they do not update the repository.

Some wescripts are declared <transaction allow="readwrite"...> but should be declared <transaction allow="readonly" > if they do not update the repository. One of the bad side effect of that is a lower usage of the L2 cache.

How to reproduce :

Install an AOB 3.4.4 version
Activate the cache debugging, see http://wiki.alfresco.com/wiki/Repository_Cache_Configuration, I have set <property name="startDelayMinutes"><value>1</value></property> and <property name="repeatIntervalMinutes"><value>1</value></property>
Activate statistics for « ContentDataCache »
Then start, upload 20 documents in the first level of the document library in SHARE, pdf docs are OK.
Push the « refresh » button in the browser with an intervel of 15 secs 10 time.
Stop Alfresco, edit /apache-tomcat-6.0.32/webapps/alfresco/WEB-INF/classes/alfresco/templates/webscripts/org/alfresco/slingshot/documentlibrary/doclist.get.desc.xml and set <transaction allow="readonly" buffersize="0">required</transaction>

Observed result :
The hit factor for « ContentDataCache » is very low when you execute first time with « allow="readwrite" », see cache2.txt
If you switch to <transaction allow="readonly" buffersize="0"> the hit factor is much higher. See cache1.txt

Remark : I think that this behavior is logical, what is wrong IMO is that we have declared doclist.get.desc.xml « readwrite ». It works because thumbnails are done in the background, asynchronousely in another transaction.

I have extablished a list of candidates webscrips that could have the same fault and that should be check in order to increase cache usage:
