Hi, We've changed the following settings:
1. Set Latency Sensitve to High ( http://www.vmware.com/files/pdf/techpaper/latency-sensitive-perf-vsphere55.pdf ) 2. ethernetX.coalescingScheme = "disable" (for all interfaces, but management on the VM) 3. Pin down memory and CPU (we run a 4 vCPU setup with 4G of RAM) That gave us a significant boost in PPS - about 80% increase under the same CPU load. I have noticed though, that the BFD sessions (there is about 15 of them on the device) have flapped a few times in the last 2 weeks, so something still requires tuning (the BFD is at 200ms x 3). I think the next step will be to try VM-FEX (which can't be ran on the same hardware that has already a N1000V, which is a pain). If we find the time we'll also test this under KVM. kind regards Pshem On Fri, 8 May 2015 at 19:50 Mark Tinka <[email protected]> wrote: > > > On 8/May/15 02:17, Robert Hass wrote: > > Hi > > Can you give some URL to recommended ESXi tweaking ? > > Or just write some recommendations here.
