Slow read speed vs. right speed RN516 and RN214
I'm experiencing much slower read speed than write speed on two different ReadyNas units - RN516 and RN214. Both are hooked to an HP Procurve gigabit switch with cat5e cables. The PC is hooked to the same switch with a cat5e cable. SMB is the protocol. Anti-virus is off on the two NAS units and off on the PC. Below are the results from NAS Performance Tester, where H: is the 516 and K is the 214.
Any ideas on what could be causing this?

How long have you been experiencing this problem?
Have you tried a different PC?
I suggest checking the network stats on the two NAS - download the log zip file and look in network_settings.log
