In one of the recent builds of Sugar for the OLPC XO, I found that “out of the box” the machine barely has enough memory to run programs. Tonight I installed the most recent operating system version, 8.2.0, and found the amount of free memory to be drastically increased:
| Total MB | Used MB | Free MB | |
| Sugar 8.2.0 | 230 | 162 | 67 | Sugar Previous | 232 | 220 | 12 |
With 55MB more free memory, I expect this machine to play a lot nicer with its users!
I used
free -m
to get these measurements.
Check out compcache with a recipe like this:
if ! `grep -q compcache /etc/rc.local` ; then
set +e
target_dir=/home/olpc/src
this_kernel_rpm=kernel-devel-`uname -r`.i586.rpm
mkdir $targetdir
cd $targetdir
/bin/rm -f ${this_kernel_rpm}*
wget http://dev.laptop.org/~dilinger/{stable,testing}/$this_kernel_rpm
wget http://compcache.googlecode.com/files/compcache-0.4.tar.gz
rpm -ivh $this_kernel_rpm
cp -af /boot/* /versions/boot/current/boot/
tar xzf compcache-0.4.tar.gz
cd compcache-0.4
make
./use_compcache.sh
echo “(cd /home/olpc/src/compcache-0.4 ; ./use_compcache.sh)” >> /etc/rc.local
set -e
fi
