[3.2.7.1] Lower speed than 3.2.7 - transfert on QNAP509-TS

[vduvernet]

Hi,

I'm testing the great QNAP NAS TS-509 Pro to evaluate its real transfert speed.

My computer (NEC Versa P570, Vista Busines SP2) is connecter to Netgear GS724AT gigabit switch
NAS, connected to the same switch.

Test:
transfert BackTrack 4 iso (bt4-pre-final.iso) 1 360 968 KB.

No other significative trafic on the network.

Time with 3.2.7 : 22s, about 45/50 MB/s
Time with 3.2.7.1 : variable time : 40s to 90s 13/30 MB/s

Downgrading to 3.2.7 solve the problem.
Upgrading to 3.2.7.1 restore the problem.

Bug ou new parameter ?

Nothing has changed in the transfer code that could possibly cause this.

Most likely explanation is that the executable of 3.2.7 in your firewall's/virus scanner's/security solution's exception list, whereas 3.2.7.1 is not and thus subject to some rather slow inspection.
