Since some time ago, the text console seems to be very slow.
For example, a compilation of a TeX file takes very long if run
just like `tex file.tex'; but when run as 'tex file.tex > /dev/null',
it gets much faster, presumably by not having to do the textual output.
Similarly for a lengthy ./configure.
Another manifestation of the difference is when I launch
a TeX compilation and switch to another X window,
completely obscuring the xterm where the compilation is happening.
If I switch right back, I see the compilation has already finished;
if I stay in the xterm window, it takes forever.
This is happening in both the text console and an xterm,
with or without running tmux (so I don't think it's tmux's fault).
Why is this and what can I do about it?
