Please make sure you measure your memory usage correctly on Linux, it is<br>
notoriously easy to get misleading info from tools like top.<br>
<br>
I use this one on Linux.<br>
<br>
$cat ~/bin/showmemusage<br>
#!/bin/sh<br>
if test -z "$1"; then<br>
echo "need a pid"<br>
exit<br>
fi<br>
<br>
mem=`echo 0 $(cat /proc/$1/smaps | grep Pss | awk '{print $2}' | \<br>
