if i'm understanding right, are you rendering and modifying your scene at the same time? why don't you try some of this:
1.- Rendering dialog allows rendering a certain portion of your animation, from time Y to time X.
At the moment I'm working on a single frame, but I need to trace a big image drawn by my wife.

2.- Divide your animation into various canvases, then call for them in a single root document.
I'm a newbie how can I make a Root document
In future it will be usefull.
Thanks because a new idea has pop up in my mind...
I will break the big image in tiles and different files so tracing image will be faster
A little crooked but I think it can work... other ideas?

for better Synfig performance...
It seems that the rendering engine renderize all the image everytime I modify an obj.
Maybe a rendering mechanism that renderize only the area of the modified obj make faster Synfig
Something like the rendering system adopted for windows in Graphical OSs that eg render only a closed window background...

3.- Use the command line render process, if the problem is the amount of time it takes for rendering your animation this will makes thing slightly faster. btw, is faster rendering a sequence of PNG images and import them into any program for Video Editing, KDEn Live, LiVES, Blender's Sequence editor for example.
I note this

4.- This last is something i tried only one time, but didn't work, this was long ago so i don't know if at this point works, in the view-port window you have the status dialog at the bottom of it, when you are editing or rendering or something you can notice by looking at it, at the opposite side but still at the bottom of the window, you have a button *reload* and an 'X' one which becomes available for stopping rendering progress, as i told you it didn't work when i used it as it did nothing, the file kept rendering somehow successfully.
It didn't work I think, it is always disabled.
Maybe I'm not able to make it work...
Thankx for your help!
