Excesive RTT if cell flooded with AP to STA traffic

I'm looking at packet loss in condition of large traffic in the cell.
I've found this interesting fact about the RTTs in the cell in some
AP, STA1 and STA2 associated.
Cell is flooded with UDP traffic, 1500B packet size, from AP to STA1.
STA2 pings the AP :
100 packets transmitted, 99 received, 1% packet loss, time 99966ms
rtt min/avg/max/mdev = 267.894/280.973/324.914/7.935 ms
Whenever, when the cell is flooded with traffic from STA1 to AP, the RTT
get normal values:
100 packets transmitted, 100 received, +2 duplicates, 0% packet loss,
rtt min/avg/max/mdev = 2.949/8.593/31.640/5.129 ms
What you think about this 300ms RTT?
I'm using hostap 0.2.0 with LinkSys WPC11 cards.
