Under Yast hard ware info, my cpu shows up twice.
Also in xosview it shows cpu0 and cpu1.  Why do I
have
two showing, is this why my system seems slow.  I
have
a 3.0Ghz P4.  How do I fix it?

Do a "cat /proc/cpuinfo", if in "flags" you have an
"ht", it's because
you processor supports hyperthreating.

Also, do an "rpm -qa | grep kernel", you should see
you're using the smp kernel
...

rpm -qa | grep kernel

Well, thats why you see 2 processors, it's because of HT
