Hi Dan, I do not know dynaTrace 4.1. so I cannot tell you anything about the improvement but would be happy to get more information about this - maybe I can adjust my ratings. As I stated above, this was not a test of APM solutions but my personal opinion and experience with the tools....
dynaTrace has a new 4.1 release - it appears to address many configuration issues as well as scalability..... which version did you use in your analysis?
Thanks, this is informative! And there is a typo on "map -dump:file=path_to_file java_process_id": it is "jmap" rather than "map", right?
This is quite a good explanation. I'm a java developer and the first time I developed in objective-c I never saw all these similarities. Nice Post!
