Computer Is Very Slow After the Installation of SuSE Linux Enterprise Server 7

Support knowledgebase (tsieden_sles7-slow)
Applies to

SLES: Version 7

Symptom

Following the installation of SuSE Linux Enterprise Server 7 on an SMP system, the system is very slow. For example, YaST2 might take up to 10 minutes to start!

Cause

Unfortunately we do not know the cause of this phenomenon. Possibly there is some kind of incompatibility between the kernel used by SuSE Linux Enterprise Server 7 (k_smp-2.4.7) and the mainboard or the utilized processors. So far this symptom was only encountered on new Intel XEON mainboards from the Supermicro company (with one CPU).

Solution

Log in to the system as root and perform an update of the kernel to version 2.4.18. This kernel is available at our Maintenance Web or on the SuSE Linux Enterprise Server 7 Patch CD3. For this purpose, please use the command: rpm -Uhv /kernelupdatepath/k_smp.rpm. The update can take several minutes. Please do not cancel the procedure. Then execute the commands mk_initrd and lilo -v and restart the system by entering reboot. Now the computer should operate with the normal CPU speed.
