First please use the update that was provided to you today for your ticket that you had mentioned and use the latest version of the DSS V6 build 4221 with your replications and provide the logs to our engineers so we can assist you on getting the speeds that you are needing.
For Ticket 1014840 the engineer did take your call to talk with you and to help you we provided you a small update. In many cases with FREE SUPPORT we may need more time to investigate your issues as fast as possible for you and this can take time.
Also there are many forum notes and references that talk about using a Bond and using a bond for replication does not help in performance, please try to use 1GbE NIC.
Concerning the other tickets I sent you an email and I think you were unfair not providing all the information and in each ticket our CTO personally contacted you. The forums are designed to help others with technical references and not Tickets to post for personal gain that are not fairly published as we did and will address them.
Let us help you to get your speed issues resolved and provide the logs to our engineers from the update that was provided to you today and with the latest build 4221.
