Re: [Springframework-developer] AOP Performance Comparisons

[Rob H. <ro...@ca...>]

All,

I ran these tests on my machine and did a little tweaking with the 
parameters to see what performance improvements could be made - here is 
what I got.

With the default configuration my figures were:

1008;945;968;929;;1109;1109;1039;1125;922;945;929;1179;

With the proxyTargetClass flasg set to true I got:

617;570;593;578;;765;719;687;726;547;546;539;765;

And with both frozen and proxyTargetClass set to true I got:

422;258;257;258;;437;406;343;414;234;234;234;453;

This is the output given by the tool and each field is nanoseconds per 
invocation for a given test. As you can see it is more than possible to 
substantially improve the performance shown for Spring in the 
performance test suite. However, in the current version of Spring you 
cannot set the frozen when using the ProxyFactoryBean. I have a fix for 
this that I used for the test which involves overriding the setFrozen 
method on ProxyFactoryBean to set another flag instead of frozen and 
then using this flag to set the frozen flag just before proxy creation. 
If everyone is happy with this fix I will commit it to CVS.
