Re: [aspectj-users] Runtime performance against different weaving options
|
Hi Leon.
In general, CTW and PCTW should be the same in performance because you just have normal classloading plus aspectjrt.jar. Only for LTW you have a "warm-up" phase because aspect weaving needs to be done during classloading. This is why you need the weaving agent (aspectjweaver.jar which also includes the runtime) on the command line. So LTW is a bit slower at the beginning, afterwards the three methods should have identical performance. Either way runtime performance will be significantly faster (not mentioning more powerful) than with proxy-based AOP approaches like Spring AOP which involves Java Dynamic Proxies and/or CGLIB proxies.
