Have a look at OutputSizeLimit and $OutputSizeLimit. You could try setting
to Infinity.

But...there is a very good chance this will not help at all to speed up
the process. Reason being, if clicking "Show Full Output" then takes a
long time, it is almost certainly because it in fact takes time to typeset
or for other reasons to print the output in question. Hence automatically
showing full output will still be slow; all it will save you in time is
that checkbox click.

This automatic output truncation behavior was introduced in version 6.
Many people, including myself, are quite happy to have it. Saves endless
time in outputting garbage, in situations where a typo or other user error
would cause a huge result. Such a feature had been frequently requested
prior to version 6.
