I've noticed something scary. My UltraBook IIi has 256 MB. Here's the output from top with nothing except JDS running:
last pid: 2314; load averages: 0.08, 0.32, 0.36 11:13:42 67 processes: 62 sleeping, 4 running, 1 on cpu CPU states: 97.4% idle, 0.7% user, 2.0% kernel, 0.0% iowait, 0.0% swap Memory: 256M real, 54M free, 228M swap in use, 435M swap free PID USERNAME LWP PRI NICE SIZE RES STATE TIME CPU COMMAND 2314 root 1 59 0 2072K 1632K cpu 0:00 0.56% top 1138 root 22 59 0 115M 42M run 0:37 0.49% java 1370 root 14 49 0 105M 18M run 0:06 0.35% java Notice that the two Java process are sucking up a large chunk of memory. Even if you only look at resident memory, these occupy well over 50MB. What are these two Java processes? Well the "big" one (42MB) appears to be running com.sun.cacao.container.impl.ContainerPrivate, and the smaller (18M) one appears to be running /usr/lib/patch/swupna.jar (-wait). Again, this is UltraSPARC platform stuff. Admittedly 256 MB is a little smallish for RAM these days, but still.... What the heck is Cacao? And why does Java want so much memory? I should probably ask this on one of the other lists than laptop-discuss, but since laptops are often more resource constrained, it still seems somewhat appropriate to raise the issue here. -- Garrett D'Amore, Principal Software Engineer Tadpole Computer / Computing Technologies Division, General Dynamics C4 Systems http://www.tadpolecomputer.com/ Phone: 951 325-2134 Fax: 951 325-2191
