I put a new fix which change the performance of MFNetDisk for ever.
Elapse time is now 67 % better than before this weekend.
Here is the email I received from a customer about the changes I have done
this weekend. This change is in the code and not the HW.
I did not ask the customer to send me this email, but he sent and I decide to
show it to you. I hope it is OK with you to receive this email.
As you can see I make advance step by step, slowly but constantly, and
really I enjoy it.
Thanks,
Shai

That is a large difference.
Even if I can save 50% of the elapsed time for HSM daily backups and volume
dumps of MPC volumes that will be a huge improvement in performance.
