I did a speed test with a colleague. We basically have identical Lenovo ThinkCentres. He has 8 vs my 4 G RAM, but I don't think that's the issue.
code: length <- 2*10^6 a <- runif(length) b <- runif(length) print(summary(lm(a~b))) Running Arch x86_64 this takes about 16 to 17 seconds. I *think* I have compiled arch=i686 and arch=x86_64 with little speed difference. On windows, this takes 7 to 8 seconds. Thoughts? ______________________________________________ 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.
