When more clients (128) are connected, the UL data traffic KPI measurement is low compared to single client. This issue is due to more CPU cycles spent on the peer lookup operation with more clients. So reduce the peer lookup operation by modifying the linear based lookup operation into the rhash based lookup operation. This improve the peak throughput measurement. Since this is a software algorithm change, it is applicable for all the platforms.
