This may explain one part of the issue.
I have done a little bit of profiling this morning, and the main culprit is the
call to getenv_f in post_get_flags for the four environment variables:
"post_poweron", "post_normal", "post_slowtest" "post_critical"
This is extremly slow on my system (before relocation). The goal of these env
variables is, I guess, to define the name of the tests that have to be run for
each post level, right ? Is this the only way to define which tests are to be run ?
