Need to get more through put between esx4i and physical system

I have an ESX4i 4.1 server setup. I'm running a Win7 VM off the local drive. I have 4 NICs setup as teaming for load balancing.

I have another physical system running Win7 64bit with a raid 5 config. I have 4nics in this system setup as intel teaming for loading balancing.

Now I copy ripped blurays back and forth. They are in the range of 30gb to 45gb. So I'm looking to get eh best through put possible.

Right now when I copy I get about 66MB /sec. Now I get that weather the ESX server has 1 nic, or nics teamed. Why is that. Should I get more through put?

How can I increase the through put. I figured with 4 nics teamed on each system, this should be faster. The nics are all running at 1gb.

What am I doing wrong?

How are you doing the copy?  In order for load balancing to work, you need to have multiple tasks driving the I/O.  If you only have one stream, you cannot load more than one NIC.

Probably, but it really depends on what you are moving.  If it is a single file, trying to get more than one stream may be difficult.  Options like BitTorrent might help, but it's an atypical application for internal data moves.  If you are moving multiple files, you could use tools such as RichCopy or its competitors.

The point to understand is that in order to get high levels of thruput associated with load balancing and similar technologies, you have to multithread the process.  And, all facilites along the path must be multithreaded including processes, storage, NIC's, etc.
