Interesting. When we had this conversation last year and I wasn't impressed with the Xaon unit, I heard every reason under the sun why that observation was wrong. One might have thought that I'd badmouthed the holy trinity.
Possibly because comment is based on the usual irrational and unsubstantiated observation.
Have you actually run one of these units alongside TAS?
Are you certain you know the "ghost" traffic is "ghost" traffic?
How have you actually assessed for any reasonable period of time that these units are beset with an unreasonable number of errors?
