I modified the PropertyUtils benchmark to use CGLIB: Method Dest Orig CGLIB? Duration -------------- ---- ---- ------ -------- copyProperties bean bean no 4,871 copyProperties bean bean yes 560 copyProperties bean map no 2,895 copyProperties bean map yes 461 About a 7x speedup (JDK 1.4.1, earlier JDKs will have greater speedup). This is implemented in the simplest possible way using code already in CGLIB; greater speedups could be achieved by writing more specialized code, but I'd guess less than another 2x faster. BeanUtils initially wouldn't show the same improvement, since it is doing a bunch of other stuff too, although some of that could be optimized eventually--indexed/mapped properties, etc. I'll probably be putting together some sort of BeanUtils-like API in CGLIB. I'll make sure that it will be easy for BeanUtils to hook into if you decide it's something you want to do. If anyone has specific thoughts as to what is most needed, feel free to write me or better yet join the cglib-devel mailing list (http://cglib.sf.net/).
