Hi all, I've got a test server running with ISPconfig and I've had a few people testing a website concurrently. The server isnt the best in the world but i've noticed it to almost collapse with just 3 or 4 people online. When I run the top command I get the following output: Code: [root@mail ~]# top top - 19:48:19 up 4 days, 5:29, 2 users, load average: 3.29, 3.52, 3.63 Tasks: 142 total, 3 running, 137 sleeping, 1 stopped, 1 zombie Cpu(s): 95.7%us, 3.7%sy, 0.0%ni, 0.0%id, 0.0%wa, 0.0%hi, 0.7%si, 0.0%st Mem: 515172k total, 432876k used, 82296k free, 35284k buffers Swap: 1048568k total, 78752k used, 969816k free, 210468k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 3374 gdm 20 0 75308 5988 3224 R 48.5 1.2 3350:32 gdmgreeter 20947 apache 20 0 40868 13m 3692 S 5.6 2.7 1:55.42 httpd 24694 apache 20 0 42920 14m 3300 S 5.0 3.0 0:16.04 httpd 18457 apache 20 0 42900 15m 3684 R 3.7 3.0 1:51.94 httpd 14214 apache 20 0 42436 15m 3652 S 3.0 3.0 0:43.03 httpd 16953 apache 20 0 42900 15m 3660 S 2.7 3.0 1:54.01 httpd 18496 apache 20 0 43520 16m 3804 S 2.7 3.2 1:53.51 httpd 19826 apache 20 0 41360 13m 3500 S 2.7 2.8 0:28.16 httpd 19840 apache 20 0 41360 13m 3604 S 2.7 2.8 0:28.92 httpd 19926 apache 20 0 42900 15m 3628 S 2.7 3.0 1:50.13 httpd 19960 apache 20 0 43156 15m 3708 S 2.7 3.1 1:47.57 httpd 20984 apache 20 0 43448 15m 3392 S 2.7 3.1 0:24.72 httpd Apart for the CPU usage being high I dont understand the Mem information. My server has at least 256MB RAM installed, but by my calculation the total mem figure only comes to about 62-64MB? Have i set something incorrectly here?
It seems your server is swapping a lot: Code: Swap: 1048568k total, [B][COLOR="Red"]78752k used[/COLOR][/B], 969816k free, 210468k cached
is that a bad thing? Like i said its only a webserver...... one other thing i've noticed is the gdm is using a lot of CPU, and i'm wondeirng if i need to have it running, i'm only accessing the server through putty, i've tried to terminate the process but it keeps restarting.
Yes, because a hard drive is much slower than RAM. Therefore swapping slows down your server. Please uninstall the desktop.
Not sure. You could search for GNOME or KDE packages like this: Code: yum search gnome yum search kde Instead of removing the desktop, you could disable it at startup. What's the output of Code: chkconfig --list ?
Lol, Lol, Lol... You don't have to uninstall gdm!!! You can stop it and if you don't need it and then activate it again. Just type Code: service gdm stop and remove gdm using chkconfig. When you need gdm then just type startx and everything shoud works. It's not necessary to uninstall the graphic manager if you have enough space. Why you are killing it? But it's also bad to have a lot of swap used, cause using your disk drive for swap is making it wears out. Edit: If you still want to uninstall it use: Code: yum remove gnome-desktop @falko, gdm is short for gnome desktop manager, for kde its called kdm
Fedora also has a nice setup script where You can easilly configure deamons started with the system. Execute the command "setup" and a text menu will appear. You'll have to look around and find the right submenu as I don't use Fedora and simply don't remember.
