As the thread states, I wonder why my RAM usage is about 56% without any application running. It turns to 58% while opening Firefox (with only one Tab/Page opened) and typing this post. Is there something wrong?
View 9 RepliesI was trying to have a go at installing MAC on my dell alongside Ub and W7. I copied the grub2 to the first part of my sda5 so as to put the mac loader in MBR.I have since repaired grub2 back to MBR.But now my beloved Ubuntu starts up then continuosly increases RAM usage till 90% then SWAP 90% even when no application is running!!
View 2 Replies View RelatedI have a desktop PC that I built back when I was a teenager, running Ubuntu 10.04 LTS and nothing else. I love it, but for one thing: the dang CPU usage hits at least 99% whenever any application besides Xorg is open and running. This doesn't affect performance too much, but if Windows XP Home Edition never gets close to 100% usage, then I figure there's something going on.

application to monitor application wise network usage?
View 3 Replies View RelatedI've come across a really strange issue with one of my RHEL servers. The "free" command shows that 7019 MB of memory are actually in use by my system, but when summing up the actual usage (or even virtual usage like the example below) it doesn't add up - the sum is far less than what is reported by "free":
Code:
[root@server1 ~]# free -m
total used free shared buffers cached
Mem: 12011 7946 4065 0 4 23
-/+ buffers/cache: 7919 4092

We are running IPmonitor to monitor the disk usage on our Linux servers. It does not seem to coincide with what is reported when running df -h. For example on a Red Hat 5.3 server - our IPmonitor shows that 85% is used on the /usr partition, however when I do a df -h on the server it shows that 91% is used. Why there would be a discrepancy? IPmonitor uses SNMP.

i have a c++ application that consumes a lot of run time memory. It is a very large project with a lot of sub-modules. My target is to reduce the runtime memory usage as much as possible. Therefore i would like to know if there is a tool that i can use to profile the code (note that i am not interested in checking for memory leaks / corruptions so Valgrind is not for my purpose) I need to know which module has the most static data like large arrays or a lot of variables to know where to start reducing.
View 3 Replies View RelatedI currently have two internet interfaces installed, one is ethernet (eth0) and the second is wireless (wlan0). Many command line applications allow you to specify which interface should be used, but many gui apps don't provide this option or at least I haven't found it. I have some questions:
1. How would I tell Firefox to use only my wlan0 interface? If it's possible in Firefox, is this also possible with Google Chrome?
2. If a program doesn't provide a command line argument to support this, is there a standalone application that could help manage preferences for multiple applications?
I just wanted to use a network bandwidth usage monitoring application. Scenario: I am using an EV-DO based USB broadband modem with a limited GB plan. For additional data usage they charge per MB. Currently I use either wvdial (mostly) or pon to start the connection. So if there is any network monitoring application which could log time used and data used for the session, it would be great. Actually debian has too many different network monitoring applications, But I am not sure which one suits well for this purpose.
View 5 Replies View RelatedI am facing an high CPU Usage 800% in a(Quad CPU, RHEL 64 bit kernel) with my C++ application .
The details are below:
1)The C++ Application has been compiled in RHEL (2.6.9-42.ELsmp #1 SMP Wed Jul 12 23:27:17 EDT 2006 i686 i686 i386 GNU/Linux)32 bit server(Quad CPU 8 cpu) in Dev lab. When this application has been tested for 12 hrs in the Dev lab, the CPU usage is varying between 20% to 50% .
However, when the above C++ application deployed in production which is RHEL (2.6.9-67.ELsmp #1 SMP Wed Nov 7 13:56:44 EST 2007 x86_64 x86_64 x86_64 GNU/Linux)64 bit server the CPU usage is found to be increasing constantly to 800%.
2)When the CPU reached to 800% in Production Server, we have taken the pstack of the C++ Application process by using the command pstack p [captured thread id ] and we found that the pstack is showing the high CPU
usage (800%) in below libraries:
If there is any GLIB /pthread library/any other differences between 32 bit and 64 bit kernel. Since the application has been compiled in a 32 bit kernel and deployed in 64 bit kernel. Please provide your support on the same.

Well, each time I run Windows XP from my VirtualBox, I see the CPU usage at almost 100%. I experience a slow system even if no programs were running on my hosted Windows XP version.
I was wondering if there is a way for me to play with the settings so I can slightly enhance the performance. My PC is relatively fast under my Linux operating system. I need to know if there are some tips that I may follow when configuring the settings of my VirtualBox so i can achieve better results.
For some reason after I close firefox , firefox-bin keeps running and it eats more cpu than when firefox was open, a lot more. Same thing with seamonkey, seamonkey-bin keeps running after it is closed.
Attached are two pictures ,
1) While firefox is running: notice the low CPU usage
2) Firefox closed, CPU is almost 50%
I am running Apache 2.2.3 on a CentOS release 5.3 (Final) with 100 Sites. I've notice that Apache is making my server Swap around 200 MBs.
"http://www.xxx.yyy.zzz/server-status" doesn't show me too much to, so I am looking the behavior of specific httpd process.
ProcessID "18753" is the one for "http://www.xxx.yyy.zzz/server-status" in my browser.
This command show me (In KBs) how much virtual memory is that specific process using:
# /etc/init.d/httpd start
# grep Private_Dirty /proc/18753/smaps | awk '{ print $2 }' | xargs ruby -e 'puts ARGV.inject { |i, j| i.to_i + j.to_i }'
3012
... Running this command a lot of times it gives me the same output, but suddenly...
# grep Private_Dirty /proc/18753/smaps | awk '{ print $2 }' | xargs ruby -e 'puts ARGV.inject { |i, j| i.to_i + j.to_i }'
21708
Something make that process (and all the others httpd process too) to use a lot more memory!
Part of my httpd.conf:
# Timeout 120

MaxKeepAliveRequests 100
KeepAliveTimeout 3

My server is running Mysql 5.1.34, vsftpd 2.0.5, BIND 9.3.4-P1 (as slave). I couldn't found anything running in the specific time that httpd processes start to use that much memory.
I have a java program that runs on Debian as a background processor. Yesterday the Java program stopped running. I looked at the memory usage, the system only had 5MB memory left, so my guess is that the java program ran out of memory to use.
However, after we restarted the java program, we could see that the free memory count started to go up. It kept going up from 5MB to over 400MB. The increase of memory happened slowly, when I measured it, I could see that with each minute passing by, there were a bit more memory added into the free memory pool, and meanwhile, the java background process was running.
I wonder why this would ever happen. It's as if our java program first brought the machine done because it consumed all the memories, then after restart, it starts to give back memories.
I have run into a problem with my desktop using roughly 50% RAM (w/o buffers or cache) while running a limited set of applications (fbterm, tmux, weechat, ncmpc, rtorrent) on the command line. This usage only increases roughly 5-10% when starting X (an addition of xcompmgr, awesome wm, zim, parcellite, 2x conky (one replacing root-tails functionality), plus firefox and other apps that may or may not be running from time to time). (h)top is reporting programs only using roughly .1-.2% per proccess and roughly 100 processes (current look at top shows 120 processes, only 32 of which are registering any usage over 0.0%) The RAM usage when in the console (which I will add is about 150MB after boot) is totally unreasonable and I need some direction on trying to find out what is using all of this RAM.
System:
Distro: Arch Linux
RAM: 2G
CPU: AMD 64 x2 4800+
HDD: 3x WD Black 750G (RAID 5 on partition 2 (swap) and 3 (root), RAID 1 on partition 1 (boot). LVM over root partition)
GPU: Nvidia 8400 GS
I have just started to have a problem with Xorg it is always using at least 30% of my CPU, and the whole system does not run smooth so if I play a video it does not run smooth, it judders, also even if I drag an icon it judders across the screen.

I have two computers running Ubuntu. I want to run the copy of Firefox that is on the remote machine. i connect to the remote in the usual way, "ssh -X fermi", which brings up a console on the remote machine, fermi. When I type "firefox", however, it starts the copy of firefox that is on the local machine. On the remote machine, "ps aux|grep firefox" confirms that firefox is not running there. Is there a way to force execution of the remote copy?Or, can I start a local copy of firefox using the remote bookmarks, preferences, etc?
