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

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.

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 : variable time : 40s to 90s 13/30 MB/s

Downgrading to 3.2.7 solve the problem.
Upgrading to 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 is not and thus subject to some rather slow inspection.
