One of my packages on CRAN contains a vignette with a benchmark. You
can check what I do here (search for "microbenchmark"):
Basically, those chunks that use microbenchmark are marked as
"eval=FALSE", and the resulting figures are static images. I run those
manually and update the images from time to time if something relevant
changed. Apart from saving compilation time, this way I don't need to
include microbenchmark as a dependency.
