You'll have to provide the code you are using for test (the plain c++ as well as the R/Rcpp hybrid) if you really want smoke this out. My guess is that you're doing something a bit wonky (and it might just be in how you are timing it), but it's impossible to say. -steve -- Steve Lianoglou Graduate Student: Computational Systems Biology | Memorial Sloan-Kettering Cancer Center | Weill Medical College of Cornell University Contact Info: http://cbio.mskcc.org/~lianos/contact _______________________________________________ Rcpp-devel mailing list [email protected] https://lists.r-forge.r-project.org/cgi-bin/mailman/listinfo/rcpp-devel
