[jira] Updated: (HARMONY-5632) [drlvm][general] Serialization
performance improvements
Posted by "Aleksey Shipilev (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/HARMONY-5632?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Aleksey Shipilev updated HARMONY-5632:
--------------------------------------
Attachment: serialBench-TGN.PNG
serialBench-TGN.PNG
16-core Tigerton measurements.
Most noticeable patches are:
1. lookupClass optimization (HARMONY-5633)
2. emptyStream bugfix (HARMONY-5635)
Still, we have the degradation.

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
