Which tool did you use to get performance reports?

Hi Jimmy
looks like you develop great library. I was pretty amazed when i found it but also there is another way how to copy objects using implicit operator. Details on this thread:
http://stackoverflow.com/questions/531505/how-to-copy-value-from-class-x-to-class-y-with-the-same-property-name-in-c
Also i did some tests using implicit operator and your library. My comments with test and test results you can view in the link above. It would be great to hear your opinion on that.

@Andriy

Are you actually seeing any performance problems? Our bottleneck is still the DB.

If you just make sure CreateMap is called just once, everything should be very fast.

Hey, Jimmy!

I just did presentation to my co-workers on AutoMapper and they are really concerned about its performance.

Please work on improvements, since we already using it in let say huge project, about 200 different entities are now mapped with AutoMapper and then sending through WCF or serializing into XMLs we send, it would be sad if in one moment we will need to be back to manual mapping.

Thanks.

Great post,
Any idea what the impact is when more types are used ?

This is good to hear, we need to update to the latest commit to get some benefits. We knew early on that we’d take a hit, and it was sizable. But that’s again one of those local optimizations that can be fixed over time.

A little Func, and little Action and you’ve got some respectable numbers now.

Great work!
