My write speed from my PC is extremely slow, it appears to start off at the expected 100mbps per second, and then drops to single digits within seconds..... I read that 6.9.1 fixed "interface timeouts on teamed NIC", but this I feel this is still prevalent. Everything was fine prior to upgrading to 6.9.0 Thanks in advance :)

Is the PC using wireless or ethernet? You say "100 mbps" - do you really mean megabytes per second? If you are using bonding, the try testing without the bond. Also, if you are using jumbo frames, try disabling them. Also, if you are using a Windows PC, can you try testing with NAStester? http://www.808.dk/?code-csharp-nas-performance

I will get an "unteamed" to follow. and yes I did mean 100MBs.

Okay, looks as though I hadn't set the teaming back to mode 3+4 (which is was prior to 6.9.0) - set to 2+3 as this gave the best performance on 6.9.0. I have now changed it back to 3+4 on 6.9.1 (prior to single NIC testing), and everything now seems to be normal with regard write speed :) Thanks for your assistance :) (presently writing a 10gb file near on 100MBs - which I wasnt able to do this morning).

Right further more, I did a quick test this morning and the expected behavour of the fault appears to be back, strange how it was fine after switching mode but non the less, for example, here is the file transfer from a test file: Starts off fine then drop to single digits as per earlier post. I will have to get a test done where it isn't using a teamed NIC.

and one without the Bond, this suggests that the bonding issue puported fixed in 6.9.1 still has issues. I will also get similar NAS test results as per request.
