remove struts.freemarker.mru.max.strong.size from default.properties
--------------------------------------------------------------------
Key: WW-3766
URL: https://issues.apache.org/jira/browse/WW-3766
Project: Struts 2
Issue Type: Improvement
Reporter: zhouyanming
Priority: Critical
if struts.freemarker.mru.max.strong.size > 0 ,freemarker will use
MruCacheStorage instead of SoftCacheStorage,and MruCacheStorage is not
concurrent,it will synchronized on every call,it will affect performance.
in TemplateCache:
CachedTemplate cachedTemplate;
if(isStorageConcurrent) {
cachedTemplate = (CachedTemplate)storage.get(tk);
}
else {
synchronized(storage) {
cachedTemplate = (CachedTemplate)storage.get(tk);
}
}
please remove struts.freemarker.mru.max.strong.size from default.properties
lets developers make their own choice.
a better solution is implements a concurrent MruCacheStorage for struts2
