yes I am interested in that too on a concrete example such as OpenDBX. but for the general case: callout and marshalling speed comparison, you can have a look at: 1) presentation @ IWST'13 http://esug.org/data/ESUG2013/IWST/Slides/04-slidesNB-IWST13.pdf 2) and the paper for more details in the proceeding http://esug.org/data/ESUG2013/IWST/proceedings.pdf Luc > There used to be a package in DBXTalk with several benchmarks, I am sure > you could reuse some....
