We are trying to figure out for a very log intensive application that requires lots of specs what the optimal configuration would be to allow it to use utilize all cores on the blade? Is there advise on this? Like should we disable hyperthreading? What's the general rule of thumb?</div></blockquote><div><br></div><div>1. Upgrade to the latest oVirt - which provides support for the latest and greatest hypervisor features.</div><div>2. What is your bottleneck - CPU, storage, network, some of each? Many times, careful NUMA pinning is a good start - after you've ensured the rest is OK (use of virtio, enough RAM and CPU per VM, storage and network configurations, etc.). Also - some applications benefit from hyper-threading, some don't - experiment with both settings.</div><div>Y.</div><div><br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr" class="gmail_msg"><div class="gmail_msg"><div class="gmail_msg"><br class="gmail_msg"></div>-- <br class="gmail_msg"><div class="m_2330011075010296602gmail_signature gmail_msg" data-smartmail="gmail_signature"><div dir="ltr" class="gmail_msg"><div class="gmail_msg"><br class="gmail_msg"></div><div class="gmail_msg">Devin Acosta</div><div class="gmail_msg">Red Hat Certified Architect, LinuxStack </div><div class="gmail_msg"><a href="tel:(602)%20354-1220" value="+16023541220" class="gmail_msg" target="_blank">602-354-1220</a> || <a href="mailto:devin@linuxguru.co" class="gmail_msg" target="_blank">devin@linuxguru.co</a></div></div></div>
