[hobbit] Hobbit Server performance

[Hubbard, Greg L]

Linux, right?  I *think* some Linux distributions glom on to any
available RAM for a disk cache, and then they give it up when the memory
is needed by something else.  I hope I am not getting Linux confused
with Windows -- that would really start the flames!

As for the time_wait -- I have no idea.  Some systems (Solaris) have a
long time out when ports are released by default, and this can cause
connections to hang around for a long time after the remote system has
closed them.  But this is just a shot in the dark.

Subject: [hobbit] Hobbit Server performance

All,

Have been taking a look at my hobbit server for the past week or so.
Wanted to ask a couple things.

The server is a DL360 G3 with two 3ghz processors and 2gb of RAM. It
does only hobbit and cricket (10 or so routers, so not a huge hit)

I've noticed the following two things:

#1. I am constantly using 100% of my physical ram (no swap really)

Mem:   2075040k total,  2051928k used,    23112k free,    52172k buffers
Swap:        0k total,        0k used,        0k free,  1744168k cached

is this normal? Not sure how to tell which process specifically is
eating up the most RAM.

#2. I am consistantly running with 2-300 ports in TIME_WAIT involving
port 1984

# netstat -an | grep TIME | grep 1984 | wc -l
253

Im not sure if this is normal either, nor am I sure if it is bad or not?
Here is the output from some of the "bb" buttons at the top of my hobbit
page. If anything stands out, any help would be apprieciated.
If I can provide any other info, let me know.

Thanks,
Jeff
