Subject: [CentOS] CentOS5 running very slowly on a core 2 duo with 4 GB RAM

> Hi, I’ve installed CentOS5.2 on an INTEL Core 2 Duo (Intel(R) Core(TM)2 Duo CPU     E6550  @ 2.33GHz), 4 GB RAM (MemTotal:      4072176 kB) and my system gets sevarel minutes to startup, specially on udev daemon. Once the system is UP, every command I run gets 100% CPU and every is very slowly at the point yum –y update never ends. The system installed by default this kernel 2.6.18-53.el5PAE. I would like to know what’s wrong with my server. Do I have to install another kernel? Can you help me?
