Subject [jira] Updated: (HARMONY-5632) [drlvm][general] Serialization performance improvements
Date Mon, 07 Apr 2008 22:59:24 GMT

     [ https://issues.apache.org/jira/browse/HARMONY-5632?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Aleksey Shipilev updated HARMONY-5632:
--------------------------------------

    Description: 
This is umbrella issue for serialization performance improvements.

For now, distribution of clean/POC is following:

Clean:
HARMONY-5634 [classlib][luni][performance] ObjectInputStream should use HashMap instead of
Hashtable for internal storage
HARMONY-5635 [classlib][luni][performance] ObjectInputStream should empty the underlying stream
in right way
HARMONY-5633 [classlib][luni][performance] ObjectStreamClass lookup improvement
HARMONY-5640 [classlib][luni][performance] ObjectInputStream.resolveClass(ObjectStreamClass
...) optimization

Dirty/POC:
HARMONY-5636 [classlib][luni][performance] java.lang.reflect.Proxy cache should be unsynchronized
HARMONY-5637 [drlvm][classloader][performance] Make ClassLoader.loadClass desynchronized while
trying to load already loaded class
HARMONY-5638 [drlvm][performance] String.intern() should use unsynchronized fast-path
HARMONY-5639 [drlvm][classloader][performance] Make native class/method/field lookups unsynchronized

  was:This is umbrella issue for serialization performance improvements
