Skype for Business 2015 Performance Issues RRS feed

  • Question

  • I have 2 pools with 12 front ends each and a SQL backend for each pool.  I currently have around 100.000 users in each pool.  Performance is good for a few days and then I begin to experience issues with FEs dropping, presenting with extremely high ping times.  The servers will recover for a time until eventually the pool will fail after losing quorum.  Rebooting the FEs resolves the issue for a few days.  Then the cycle starts again. The FEs and SQL are on VMWare.  Running Server 2016.  We have found buffers on the NICs filling up on the VMs and have expanded the buffer size.  I have had a premier case opened to look at my Skype deployment and after uploading data, nothing has been found wrong with my deployment.  Has anyone seen anything resembling this type of issue?  The VMs are built to MS specifications.  I am lost as to what could be the cause.
