Packages of some languages rely heavily on propagation. R is one
example. Since the generated =E2=80=9Cmanifest=E2=80=9D file of a Guix pro=
file records
entries for all propagated packages, this can get really big really
quickly.
A profile consisting only of four R packages (r-seurat, r-cistopic,
r-monocle3, and r-cicero-monocle3) results in a =E2=80=9Cmanifest=E2=80=9D =
file that
weighs 7.1MB. At the MDC I repeatedly encountered manifest files that
are exceeding 24MB.
Simply reading that big a file with
(call-with-input-file "huge-manifest" read)
takes several seconds. On the MDC cluster I observed a delay of about
27 seconds.
Disabling read positions with (read-disable 'positions) significantly
speeds this up (18s vs 27s), but it=E2=80=99s still very slow.
We may be able to speed things up by supporting definitions or
references in manifest files, so that we don=E2=80=99t need to repeat a sub=
-tree
when generating the file.
