Difference in Mem usage ?
Hi All,
I have a pair of sun ultra 5_10 with SunOS 5.5.1.
Both are almost equally patched and set up with simillar applications.
host# uname -a
SunOS host 5.5.1 Generic_103640-24 sun4u sparc SUNW,Ultra-5_10
Even though both have
same amount of RAM ( 512 Mb ) ,
Swap,
and same set of processes running,
they show different values of free memory in "top". They difference is close to 50 Mb.
I had a look at few processes and compared the rss output in ps, they differ!.
Can anyone tell me why is this ?..
Eg:
host1# ps -ef -orss,vsz,comm | grep init
288 448 /etc/init
1136 1880 /usr/openwin/bin/xinit
host2# ps -ef -orss,vsz,comm | grep init
136 448 /etc/init
1120 1880 /usr/openwin/bin/xinit
The host2 is showing 50~60 Mb as free, where as host1 has only 10~15Mb free.
Thanks in advance..
