only a couple of transport layer flows running through this aggregation?
I used IOMeter to test it ,what shall I do?

It looks aggregate two nics get two nics throughput (about 200MB/s)
aggregate three nics still get two nics throughput (about 200MB/s)
aggregate four nics  get three nics throughput (about 300MB/s)

As Jim stated in his previous reply your traffic does not appear to be balanced from the last output you provided. In the aggregation of three NICs, only two NICs were sending and only two NICs were receiving.
