[Bioc-devel] Check time on macOS (MIRit)

To be a bit more clear and vague at the same time: currently, some of our
macOS builders exhibit weird slowdowns when the build system is run
automatically compared to running builds "by hand". This is pretty weird,
and hopefully we can figure out the cause and fix it. Specifically, builds
on kjohnson3 is (at the moment) weirdly slow.

Best,
Kasper

We need a bit of internal discussion before committing to this

notion.  I

will get back to the list on this.

Dear Vincent, thanks for your answer. So, at least for now, can I

ignore

the warning on macOS for the submission of MIRit?

Thanks Jacopo.  You shouldn't have to struggle.  We are aware of
disparities of platform
performance and are working to improve the build process.  It will

take

time.  I believe that
achievement of acceptable timings on the linux platform should be the
key goal at
this time.

Dear developers,

I am struggling to reduce R CMD check times for my package, MIRit,

on

macOS. The check on linux takes 4 minutes, while on macOS it needs

9/10

minutes. I have severely reduced the size of examples and tests,

which

now
use smaller datasets and cached resources.

On linux, unit tests require 30 seconds more or less, and examples

40

seconds. On the other hand, macOS tests take 100 seconds, and 75 for

the

examples. The issue is that sometimes the check runs in less than 10
minutes, sometimes it needs a little bit more.

However I am out of ideas on how to further reduce examples and

tests...

The vignette is really extensive, but since SPB uses the

"--no-vignette"

option this should not influence heavily on this behavior, at least

to

my
understanding.

Sorry for bothering you,
Best regards,
Jacopo
