We just upgraded some of our servers to OESNW65sp5. I have been
monitoring them since the upgrade and on 1 of the servers we are
experiencing high utilization at times (our webserver), normally it is
very low. One thing I noticed is it now shows 2 processors in the monitor
screen, but there is only 1 in the box. It appears this is because of
hyperthreading ? When the utilization is high, one of the processors
shows max utilization. Can the hyperthreading be causing the high
utilization? If you do not think it is causing the problem, is it best to
disable hyperthreading anyway?
