---------------------------------------
Summary: [perf] use a preinitialized table of unique ids for
UIViewRoot.createUniqueId(...)
Key: MYFACES-3823
URL: https://issues.apache.org/jira/browse/MYFACES-3823
Project: MyFaces Core
Issue Type: Improvement
Components: JSR-344
Reporter: Leonardo Uribe
Assignee: Leonardo Uribe
Thinking about ways to improve MyFaces, I have realized we can use a table of
preinitialized ids in UIViewRoot.createUniqueId(...). In that way, we can save
some HashMap.get(...) calls and avoid instantiation of ids we can already know
how they look like beforehand. A good number is preinitialize the first 50 ids
for ResourceDependency components and other generated components.
I think it is worth to use Integer instead Long for the unique id generation
too.
