The sentence is not the best English, but replacing "one" to "on" will not help, I think. > if I remember correctly, the RTS/CTS was added to fix 6000 performance > issue 2 years ago. Did you see the similar performance downgrade issue > on other devices beside 5000? No, I think only 5000 ware afected (also with random connection hangs). Patching and using cts-to-self on 6000, give slightly better performance here with 6300 adapter: vanilla 6300 5Ghz: 8.13 8.03 8.13 8.03 8.19 avr 8.1020 std 0.070143 patched 6300 5Ghz: 8.60 8.59 8.60 8.41 8.57 avr 8.5540 std 0.081425 vanilla 6300 2GHz: 4.06 4.39 4.60 4.70 4.80 avr 4.5100 std 0.293770 patched 6300 2GHz: 4.94 4.90 4.94 5.05 4.88 avr 4.9420 std 0.065727 I plan to do more testing, but not yet (except 5000 adapters I have quite good performance).
