<div dir="ltr">Hi Yaniv,<div><br></div><div>It wouldn't be an issue if all actions (create an external network, import it and assign to some oVirt clusters) would take less than a second. I don't know if it's possible in oVirt 4.1.x or 4.2.x. When oVirt is used in CI to provision VMs, every second matters.</div><div><br></div><div>OVN itself can create new logical switch in 16ms, when it has a thousand of logical switches. It can also be queried very fast as OVSDB protocol allows to request only one network.</div><div><br></div><div>Thanks,</div><div>Roman</div></div><br><div class="gmail_quote"><div dir="ltr">сб, 2 дек. 2017 г. в 9:55, Yaniv Kaul <<a href="mailto:ykaul@redhat.com">ykaul@redhat.com</a>>:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="auto"><div><br><div class="gmail_extra"><br><div class="gmail_quote">On Dec 1, 2017 6:59 PM, "Roman Bolshakov" <<a href="mailto:roolebo@gmail.com" target="_blank">roolebo@gmail.com</a>> wrote:<br type="attribution"><blockquote class="m_1813107400787534582quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div>Hi,</div><div><br></div><div>We're using for OVN provider for half a year and noticed a few performance issues when networks are created programmatically:</div><div><br></div><div>1.
