Experiencing poor throughput on a windows VM (ESXi 6.0 VM hw 11) in FT mode?

Recently seen this on the vmware discussions and was able to recreate the issue as was interesting in using the feature in 6.x (FT is something that has interested me but always found it preferable to employ more traditional HA methods/recommendations).

Indeed did notice in the lab a noticeable drop off in performance, such that latency would increase, packet loss wasn’t occurring however but it would manifest itself by poor video/streaming performance(eg stuff that would give the vCPU a good “kick”)

Luckily a silver bullet was on hand, once patched up “regular” performance resumed and throughput returned to normal
