In your startup file, I see:
374.858 001.193 001.193: sourcing
/home/neon/.vim/plugged/vim-gutentags/autoload/gutentags.vim

611.846 234.541: VimEnter autocommands
611.854 000.008: before starting main loop
I don't understand how this works.
Isn't it youcompleteme.vim which is slow? since the timestamp
goes from 377.927ms to 610.942 ms.
In the original post, you said that startup took 2.6 sec but we see
it's much faster than that from vim --startup.
In my set up, youcompleteme.vim also seems to be the slowest step.
But it's faster than for you.
Did you build with -O2? Consider posting the output of
the `vim --version` command.
For comparison, this is my startup log file on
xubuntu-22.04 \(remotely access via ssh):
