It is true that CPU affinity is designed to prevent the dump of valuable CPU cache. My thought is that if you are trying to prevent CPU contention, you could use CPU affinity to prevent 2 postmaster processes from running simultaneously on the same die. Am I out to lunch here? I've not worked with CPU affinity before, so I'm not familiar with the intimate details. -- Jord Tanner <[EMAIL PROTECTED]> ---------------------------(end of broadcast)--------------------------- TIP 5: Have you checked our extensive FAQ? http://www.postgresql.org/docs/faqs/FAQ.html
