Hey guys, I've been pulling my hair out about this for ages now, and even though this isn't a WHS forum, I figured it can't hurt to try and ask some of the guru's here for help. This is for a HP EX490 box by the way.
I can't get decent file transfer speeds. I am using 2 different methods to move files, and they both behave differently.
With TeraMove I generally get on the order of 90MB/s for the first 1GB of data (all of the sudden, the gears stop moving at 1.04GB), and after my data speed slows down to 2.5MB/s for the remainder of the file transfer. This is true for any file. With the default windows explorer utility I can generally move data at around 30-40MB/s. The speed slowly diminishes over time, and eventually it comes to a near standstill.
To eliminate variables, I'm doing a direct connection between my desktop at the server with a network cable (CAT 5e, no switch in between).
I've tried multiple cables (although given that the cable shouldn't care when I hit 1GB of data transferred I can't imagine that being the problem).
I've used the WHS drive balancer utility.
Data Duplication is disabled for the share I'm transfering data into.
Twonky Media Server is disabled.
I've installed the most recent NIC Driver from Realtek's website.
On the server I have checksum offload dissabled, flow control disabled, green ethernet disabled, jumbo frame disabled, large send offload enabled.
On the desktop I have flow control disabled, IPv4 Checksum Offload disabled, Jumbo Packet set to 9014 Bytes (no disable option). TCP Checksum Offload disabled, UDP Checksum Offload Disabled, ...
I'm having transfer speed issues w/ other computers as well, so I'm sure it's not something wrong w/ my desktop.
There has to be something that can be done to bring these file speeds up to 80-ish MB/s where they should be at. Suggestions?
