Hi, i'm building a small document with LuaLaTeX, for that i have use the following manifest
--8<---------------cut here---------------start------------->8--- (specifications->manifest (list "texlive-amsmath" "texlive-todonotes" "texlive-xpatch" "texlive-collection-luatex" "texlive-collection-basic" "texlive-latexmk" "texlive-scheme-basic" "texlive-biber" "texlive-booktabs" "texlive-microtype" "texlive-koma-script" "texlive-lipsum" "texlive-pgfplots" "texlive-biblatex")) --8<---------------cut here---------------end--------------->8--- This command takes quite a long time --8<---------------cut here---------------start------------->8--- guix time-machine --commit=21b718f4d6c3ded8ef50d12f6e9ae6474f74620f \ shell --manifest=guix.scm -- latexmk -lualatex -auxdir=.tex-cache main --8<---------------cut here---------------end--------------->8--- To be precise: --8<---------------cut here---------------start------------->8--- Command being timed: "guix shell -m guix.scm -- latexmk -lualatex -auxdir=.tex-cache main" User time (seconds): 14.60 System time (seconds): 87.58 Percent of CPU this job got: 99% Elapsed (wall clock) time (h:mm:ss or m:ss): 1:43.18 Average shared text size (kbytes): 0 Average unshared data size (kbytes): 0 Average stack size (kbytes): 0 Average total size (kbytes): 0 Maximum resident set size (kbytes): 179368 Average resident set size (kbytes): 0 Major (requiring I/O) page faults: 0 Minor (reclaiming a frame) page faults: 118914 Voluntary context switches: 2146 Involuntary context switches: 3693 Swaps: 0 File system inputs: 462280 File system outputs: 6584 Socket messages sent: 0 Socket messages received: 0 Signals delivered: 0 Page size (bytes): 4096 Exit status: 0 --8<---------------cut here---------------end--------------->8--- Running `latexmk -lualatex -auxdir=.tex-cache main` takes under 10 seconds. These times are for fresh builds, i.e. the intermediate files have been removed. Still even recompilation is many times slower with guix provided LuaLaTeX than it is on Arch. I should also note, that using the modular TeX packages actually helps here, with the full TeXlive package the compilation time is nearly twice as much. Another thing i noticed is, that a directory with the following structure gets created: --8<---------------cut here---------------start------------->8--- { └── gnu └── store └── 3wsicprhgxhcncaf5mv26wwbhhh8p6yj-profile └── share └── texmf-dist └── luatex-cache └── generic ├── fonts │ └── otl │ ├── lmroman10-italic.lua │ ├── lmroman10-italic.luc │ ├── lmroman10-regular.lua │ ├── lmroman10-regular.luc │ ├── lmroman12-regular.lua │ ├── lmroman12-regular.luc │ ├── lmroman17-regular.lua │ ├── lmroman17-regular.luc │ ├── lmromanslant10-regular.lua │ ├── lmromanslant10-regular.luc │ ├── lmsans10-bold.lua │ ├── lmsans10-bold.luc │ ├── lmsans10-regular.lua │ └── lmsans10-regular.luc └── names ├── luaotfload-lookup-cache.lua ├── luaotfload-lookup-cache.luc ├── luaotfload-names.lua.gz └── luaotfload-names.luc.gz 11 directories, 18 files --8<---------------cut here---------------end--------------->8--- This is obviously for caching purposes, but (seemingly random) having a folder named '{' in your working directory certainly is confusing. mfg
