I just...Hi Balazs, thannks for your quick response. I just asked you because I've been not able to understand well when to use SMT (or not) in combination with EC and VP. I'm gonna keep searching and read your link above. <br />Keep that great blog. Believe me it's a big source of knowledge for those which start with this wonderfull OS.Anonymoushttps://www.blogger.com/profile/07042577289733219379noreply@blogger.comtag:blogger.com,1999:blog-5391325129965939458.post-84557095893922305122013-12-30T16:07:53.277+01:002013-12-30T16:07:53.277+01:00Hi, these ratios are taken from IBM sources (e.g. ...Hi, these ratios are taken from IBM sources (e.g. Nigel Griffiths), so I am just communicating those here as well. Regarding SMT I did not find any generic rule of thumb. I wrote some info about intelligent SMT threads, which probably helps you to answer your question: http://aix4admins.blogspot.hu/2011/08/commands-and-processes-process-you-use.html<br /><br />-Balazsaixhttps://www.blogger.com/profile/11198511213080760662noreply@blogger.comtag:blogger.com,1999:blog-5391325129965939458.post-51682811228163631452013-12-30T10:33:02.760+01:002013-12-30T10:33:02.760+01:00Hi,

Thanks. ;)<br />Now the question:<br />You say here the "combination" of EC/VP as:<br /><br />EC: 0.05 - 0.6 --> VP=1<br />EC: 0.7 - 1.4 --> VP=2<br />EC: 1.5 - 2.3 --> VP=3<br /><br />But you not include SMT. Do you recommend ALWAYS to use SMT2/4?Anonymoushttps://www.blogger.com/profile/07042577289733219379noreply@blogger.comtag:blogger.com,1999:blog-5391325129965939458.post-53565372694476856262013-08-22T08:15:06.565+02:002013-08-22T08:15:06.565+02:00Hi, you should check your configuration:
