We have installed Centos 6.4 in System X3750 M4 IBM Server. But the server is not showing the performance of at-least a normal Desktop Configuration. We haven't done any performance tuning in the Server.

Soon after completing the installation we checked the system monitor in the system, and there it shows total 32 CPUs and only about 3 CPUs have load, others are in idle mode.

Our System Configuration is:

IBM System x3750 M4 Server

300GB * 4 HDD

32GB RAM

2 Quad Core * 4 ProcessorsNos = 32 CPUs

Intel Xeon Processor

Partition:

RAID 1

2 HDDs in one RAID.

Centos 6.4 Server

java version "1.7.0_25"

Database : mysql Ver 14.14 Distrib 5.1.66, for redhat-linux-gnu (x86_64) using readline 5.1

JBOSS 6 Application Server

Apache Tomcat 7.14

What all Basic configuration must be done in the Centos 6.4 to achieve a good performance?

We are newbies in this field , i.e in server configuration and all. So please help us.

Thanks in advance.

  • What does "at-least a normal Desktop Configuration" mean? Do you have a performance baseline? Where are your metrics? What are you measuring? What historical data do you have for those metrics on your application’s previous server. Also please read [on-topic](http://serverfault.com/help/on-topic), [professional capacity](http://meta.serverfault.com/questions/4111/what-is-a-professional-capacity) and [How can I ask better questions](http://meta.serverfault.com/questions/3608/how-can-i-ask-better-questions-on-server-fault). –  Sep 03 '13 at 03:38
  • After the installation of Centos 6.4 in the specified server in my previous post; while I am taking any application like gedit or konqueror the application hangs and a I feel a slowness in the whole system. This will be more when I am taking the System Monitor Tool. Please help me in sorting the issue. – NEVIN ALEX Sep 03 '13 at 06:07

Try to open a terminal window and issue this command: top -b -n1 > /root/topcmd, this will save the output of top to the file /root/topcmd, open it with a text editor and copy its contents here to find out whats going on. Probably some program or service is missbehaving
