Writing speed became so slow after upgrade to 6.5.1 #27294735

 

Hello,

 

I recently got new RN104 and now I am having performance issue on writing data there.

I put new HDDs for that. (2 of Western Digital Red 6TB and use them as RAID1 ).

Actually I called support and got another RN box and what I saw was

the writing speed was good at FW6.2.0 and FW6.2.5 but once it is upgraded to 6.5.1 the Writing speed become 1/5...

FW6.2.0 : Sequential Write (T= 1) :    65.227 MB/s

FW6.2.5 : Sequential Write (T= 1) :    55.156 MB/s

FW6.5.1 : Sequential Write (T= 1) :    11.533 MB/s

So I think that is FW issue.. but I cannot go back to 6.2.5 now..

I use Windows 7 as client and at RN box, only enable SMB, HTTP, HTTPS ( no Virus Check). set SMB as SMB2 using SMB Plus. Disabled IPv6, Factory Reset already done but no help. Change MTU value also did not help.

Can someone please help ?

With current speed, I cannot use that box for my scheduled data backup purpose..
