Summary: performance issue after revision 746425
Product: Tomcat 7
Version: trunk
Platform: PC
OS/Version: Windows XP
Status: NEW
Severity: normal
Priority: P2
Component: Jasper
AssignedTo: dev@tomcat.apache.org
ReportedBy: robert_goff...@yahoo.com
Revision 746425 changed at least 2 files: ELResolverImpl and ELContextImpl. I
believe this causes an unnecessary performance regression in these two files.
In ELResolverImpl, every time that getDefaultResolver is called with security
enabled, a new Object is going to be created. It appears as if
getDefaultResolver is going to be called a lot and this could significantly
hurt performance. I understand changing the DefaultResolver to be private and
allowing access to it through the getter method, however, I don't believe a new
object needs to be created every time the method is called.
In ELContextImpl, why does a new FunctionMapper need to be created for each
ELContextImpl?
Thanks.
