we're using a toolchain based on texlive 2015 and I made a try replacing it with the new released version of texlive 2017. As testobject I used or current document (~650 pages). I found out that a complete
latexmk run for generating the pdf-document is about 50% slower than before.
Well since mid 2015 there have been a lot of changes to the packages, the compiler and scripts etc. So I now looking for a way to find the culprit.
Is there a way (best practice) to get detailed information about the compilation run and how much time was used for the different compilation steps (package, font loading, idx, page, toc generation etc.)?
Our toolchain is based on lualatex as compiler and latexmk as build script as well as many ctan packages.
P.S.: I also had a look at these threads but couldn't find any suitable answer for my situation.
