[Cin] Playback Slows Down Immensly Durring Transitions

I attach the file with the messages from the terminal. I tried to do
this test just to see if it improved the slowdown. But it's not
important, I would say not to waste time on it.

With my normal installation I have the following results:

https://www.dropbox.com/s/h8p4tyvx2snwiyi/transition.mp4?dl=0

I summarize the results:

mp4 --> wipe --> png --> dissolve --> 3gp/cut/3gp --> slide --> mp4
 30      29       29      21 (png?)    30  28  30       29       30 Fps

I can tell I don't have any particular problems.

Repeating the test by activating "Play every frame" and "autocolor
assests" to stress the system more, the result is similar. Maybe 1 fps
less, but there is no noticeable difference.

Repeating the test using the compile with modified CFLAGS (-O2) and
then starting from:

# /path/bin/./cin

instead of by:

# /path/cinelerra/gdb ./ci

(which as you can see from the attachment does not work for me) I
still get similar results: I rarely go down to 29 fps.

NOTE: in the edit "neve.3gp" I cut a part of the shot to shorten it.
The result is to have a cut in the middle of that shot. When the
cursor passed over this cut I had a slowdown similar to those in the
presence of transitions. (little, as I have already said, about 1 fps,
you see in the video at 15s). So I wonder if the slowdown is due to
the edges of the edits instead of the transitions. In fact, the
transitions are always on the edges of the edits, of course.
