That's absolutely alright as Linux manages memory in a different way than windows. You should read my article "Linux server loads explained" in articles section. Try using free -m and see the explanation in that article.


Hi,

Thanks. - That is an interesting article.

free -m shows:
total used free shared buffers cached
Mem: 998 941 57 0 171 455
-/+ buffers/cache: 314 684
Swap: 1992 0 1992

I am still concerned about the amount showing as used, even though the buffer shows 684 free. The machine has 1GB of ram.

Does this look normal to you ??

Also, here is a copy of the latest 'top' too:

top - 07:41:45 up 1 day, 7:32, 2 users, load average: 0.00, 0.00, 0.00
Tasks: 115 total, 1 running, 114 sleeping, 0 stopped, 0 zombie
Cpu(s): 0.0% us, 0.0% sy, 0.0% ni, 100.0% id, 0.0% wa, 0.0% hi, 0.0% si
Mem: 1022928k total, 964280k used, 58648k free, 175212k buffers
Swap: 2040212k total, 4k used, 2040208k free, 466568k cached

Thanks again,
Daniel

Yes, it looks normal to me. You can see the percentage of memory usage by each application/process using the "ps auxf" command.

Try to disable Spam Assassin and other things like mailing lists if necessary. Based on current statistics, it looks like a Perl-based forum hosted on the server you are eating most of the CPU. Consider making a PHP based forum or phpBB as MyBB.

First of all, you need to reduce the server load by using several methodologies including PHP and MySQL optimization, maintenance of server load balance, reducing system load and many other noticeable ones.

RE: Server Overloaded - Optimization Needed - Heavy MySQL and PHP

My server has already been overloaded before but it is not like this that the loading speed has been totally affected. What do you suggest that I do on this matter?

Attempt disabling spam assasin plus other things such as mailing lists if not essential. From the present stats, this seems as there is a Perl based forum hosted on the server that is eating up mainly of the CPU.
