[Rd] rhub vs. CRAN fedora-*-devel, using armadillo & slapack

[RICHET Yann]

Thank you for your answer.
In facts, 10 threads are asked by armadillo for some LinAlg, which backs to two threads as warned. But I cannot imagine this costs so much time just for that...

A deeper analysis of time spent seems to point that a large time was mainly spent on testthat and Rcpp dependencies compilation... But other recent packages depending on these also are not spending so much time.

CRAN team, as I failed to reproduce the issue with rhub dockers, 
- is there any reason that could explain that fedora-*-devel is so slow for this package or compilation of Rcpp/testthat ?
- is our slapack a possible source of... anything ?
- are we the only package which embeds "standard armadillo" and tries to deal with simple precision lapack issues on fedora ?
- is there any chance that I can get a deeper log of what happened ?

Best regards,

Yann

Oops, it was 10 threads not 30 but it does not change the nature of a possible issue.
