Subject [jira] Commented: (HARMONY-5404) [classlib][luni][reflection][performance]Proxy instances can be optimized
Date Fri, 18 Jan 2008 19:31:34 GMT

    [ https://issues.apache.org/jira/browse/HARMONY-5404?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12560515#action_12560515
] 

Evgeniya Maenkova commented on HARMONY-5404:
--------------------------------------------

Currently each method of new instance of java.lang.reflect.Proxy, generated in package org.apache.harmony.luni.internal.reflect.ProxyClassFile,
contains Class.forName and Class.getMethod calls. But this information is availably in static.
This way we can avoid 2 calls in each method of Proxy.

This approach implementation gives up to 3x boost on attached micro bench:
on patched version:
8
456x456x
true
result: 12719

on clean version:
8
456x456x
true
result: 3890
