En utilisant le test iperf (Mon lien) , il serait bon de vérifier le débit de ton installation. Au moins cela te fournira un indicateur sur les perf de transfert réseau (ayant un impacte sur la vitesse d'écriture sur ton NAS).
ipkg install iperf
Installing iperf (2.0.4-1) to root...

Configuring iperf
Successfully terminated.
Lancer le serveur avec la commande suivante sur le NAS :
iperf -s -p 3333
Résultat
------------------------------------------------------------
Server listening on TCP port 3333
TCP window size: 85.3 KByte (default)
------------------------------------------------------------
Lancer ensuite depuis le client la commande suivante :
iperf.exe -c 192.168.1.24 -w 2000K -i 3 -t 10 -r -p 3333
------------------------------------------------------------
Server listening on TCP port 3333
