Hello all,
i was testing some features of ralink rt2860 driver. i saw a bit weird
results. below is the result of what i saw. The throughput achieved doesn't
change much when the MPDU aggregation in an AMPDU goes from 3 to 8. And
also, the driver doesn't seem to aggregate more than 8 MPDU's in an AMPDU
even when the BA win size is set to max of 64. i was testing this by fixing
the rate at MCS 15
Is there anything else i need to do to force the driver to aggregate more
MPDU's in an AMPDU ?
BA Win Size No. of MPDU's Throughput(Mbps)
aggregated
1. 64 7-8 85.7
2. 32 6-7 84.2
3. 16 6-7 81.7
4. 8 6-7 79.9
5. 4 5 84.7
6. 2 3 71.8
7. 1 2 73.5
Thanks
ram
