I saw this problem some days ago, too. And: You are right. Using realtime applications is quite unusable with stock sw-stack. That's one reason amongst others why I don't use networkmanager at all, but solely wpa_supplicant and managed dhcpcd via wpa_supplicant logfile while starting. But this is not the only point, which breaks realtime applications. Another one is rekeying (4 way handshake), which is broken when executed while network load.
