[Scummvm-devel] Memory footprint

[Max Horn]

Yo folks,

recently I made a memory profile for ScummVM running CoMI (well, the  
start of it at least). I marked where the biggest chunks of memory  
were used. While I myself currently have no time to make any use of  
it, maybe somebody is interested in using this to trim away some fat  
from ScummVM in general and the SCUMM engine in particular.

One idea I had: Maybe one can safe 300-700k in NutRenderer::loadFont  
(well, for CoMI, at least), by not pre-decoding the fonts, but rather  
decoding the compressed data on the fly (i.e. load the font file to  
memory, don't unpack it, but rather use it on the fly).

There are many other things eating up memory in ScummVM. This  
particular sample was only for the first few minutes in CoMI, it's  
probably a good idea to take a longer sample; and other SCUMM games /  
engines might benefit from a trimming, too. After all, our smaller  
backends all benefit from reduced memory footprints.


Bye,
Max
