Hi, Ilias. I think that is not ok to compare performance in different plataforms of different machines. To compare times, is necessary you execute the code at the two plataforms (Linux and Windows) in the same machine. But the problem here is other. The advanced users explained it well. So I ask them: Is it possible build the R (under Linux) and force the compilation make it in 32 bits (at a 64 bits machine)? Thanks to all, Cezar Freitas

Both R and libraries are compiled from source. These are the results. user system elapsed 23.861 0.812 25.065 It seems better than the windows. Is there a posibility that on linux you have a big workspace, or something is consuming your memory and thus R is forced to use swap memory? Just a speculation. Ilias PS. BTW It uses only one core. 2009/6/26 Cézar Freitas <cafanselm...@yahoo.com.br> #windows time # user system elapsed # 27.81 0.00 27.82 #linux usual compilation time # user system elapsed # 52.635 0.016 52.748 #linux (my compilation) time # user system elapsed # 52.567 0.016 52.588 #==============END OF CODE ____________________________________________________________________________________ Veja quais são os assuntos do momento no Yahoo! +Buscados http://br.maisbuscados.yahoo.com [[alternative HTML version deleted]] ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code. ____________________________________________________________________________________ Veja quais são os assuntos do momento no Yahoo! +Buscados http://br.maisbuscados.yahoo.com [[alternative HTML version deleted]]
