If you are in graphics mode, start loading the frames and then disable or
delete the representation using graphics mode. The overhead required by the
graphics will be removed. Then when the trajectory is fully loaded recreate
the representation.

Alternatively use command line/script to load the trajectory which will
take the same time (almost) as the time required using the steps above.

If your time step and record frequency is too close you can choose to skip
some frames assuming that it doesn't result in a loss of useful

Removing waters from a trajectory, if you are only interested in a protein
will also speed things us as the desolvated trajectory will be much small
smaller and hence will load faster.

Just some things to think about.
