The elapsed time is below 1s, but the "user" time (CPU time spent in the process) is 7 to 13 times that. This suggests that your code resulted in starting more threads than CRAN allows (up to 2 if you have to test parallellism). Are you using OpenMP? data.table? makeCluster()? It's simplest to always to default to a parallelism factor of 2 in examples an tests, because determining the right number is a hard problem. (What if the computer is busy doing something else? What if the BLAS is already parallel enough?) > Moreover, is there any insight as to why this would happen on the > third update of the package rather than on the first or second? The rule has always depended on the particular system running the checks (five seconds on my 12-year-old ThinkPad or on my ultraportative with an Intel Atom that had snails in its ancestry?). Maybe some dependency of your package has updated and started creating threads where it previously didn't. -- Best regards, Ivan ______________________________________________ R-package-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-package-devel
