After adding TcpAckFrequency to a Server 2003 box and setting it to '1',
here is what the VSAM Redirector Loader statistics showed.

TcpAckFrequency = default:
4,771,938 records 
13,361 seconds for Overall Duration
7,446 seconds for Transfer Duration 

TcpAckFrequency = 1:
4,781,173 records
11,487 seconds for Overall Duration 
2,652 seconds for Transfer Duration

Looks like the TcpAckFrequency parameter has a huge affect on transfer
times.
