Stablebit Drivepool Poor Network Performance

Hey all, recently installed Drivepool and scanner on my NAS

It's running Windows 7 64bit, with an i7 975 and 12 GB of ram.

I'm running 2 HGST 4TB 7200RPM drives, and 2 WD 4TB RED 5400RPM Drives in 1 pool, with 2x real time duplication.

I've turned on all the performance options, and turned on Background I/O in Scanner.

Copying files over the network to the pool is much slower than copying to a bare drive.

Copying a 30GB file results in ~110MB/s to a bare drive, which is about as high as a Gb network can copy at,

but copying to the drivepool results in only 60-75 MB/s.

Copying large amounts of small files also result in a 25% Performance decrease.

EDIT:

I fixed the problem by turning off balance immediately in the options, that was what was causing the speed issue.
