Spring AOP vs Aspectj : Performance

[shivnarayan]

Hi,

From my understanding spring AOP is based on dynamic proxies where as aspectj is based on bytecode transformation technique. Based on difference performance comparison blogs I think aspectj is much faster than spring AOP.

Guys, can you please help me in deciding if I should use aspectj instead of using spring AOP. because aspectj offers more performance. As well spring framework very well permits use of aspectj along with spring.

Karld,

Considering above benchmark, spring is the slowest performer, and aspectj would be the best candidate for AOP. Hence my take : aspectj AOP with spring framework would be the best impressive combination.

The time is in nanoseconds so based on your application load it might be negligible difference.
Use developer convenience to decide which framework to use

The real question is what are you going to use AOP for in you app. If you are not familiar with AspectJ they could a learning curve, but spring AOP is pretty easy. If you needs are simple, I would go with spring.
