Are we talking about same ubiquity m5 airmax? rocket m5? BY FAR I have never seen such figures even on the most ideal signal/better noise level. For PtP < 8k-9k. For PtMP < 2-3k. And these figures are very dependant on distance, due the ACK protocol, if distance increases, the airtime silences increases and performance decrease.

We are talking about ubnt rocket M5 airmax. Without packets aggregation it really has 5K pps. For example, 802.11a gear ( Ubnt Nanostation 5, AR 2315 Atheros MIPS 4KC, CPU 180MHz) has only 4K pps. Look at graph 802.11a ( no packets aggregation ) Throughput vs packet size.
Packets aggregation of 802.11n systems increases max pps. You may simply measure max pps by testing link by iperf UDP duplex 64 bytes packet size. Rocket M5 with 802.11n aggregation passes in lab only Rx 5-6 Mbps + Tx 5-6 Mbps duplex UDP packet 64 bytes size, that is equal to 22K pps. In aggregation Off mode Rocket M5 passes 1.2 +1.2 Mbps duplex UDP packet 64 bytes, that is equal to 5k pps.
Ubnt link pps depends on besides distance also on packet aggregation level , especially in multipoint, where aggregation falls with increasing number of served CPEs, that causes pps and throughput degradation.
We can see also the same behaviour of ubnt AC. ePMP also aggregates UL and DL subframes in multipoint, but it is different from ubnt packet aggregation, based on 802.11n protocol, and ePMP has not such throughput degradation as ubnt (N and AC) has due to among other things also pps reduction.
