I recently installed centos on my pi3. The performance is good, however when I started to mess with wifi the network performance started choking. I have around~500ms and 1-10% packetloss locally to my router. This is on the ethernet interface and NOT on the WiFi interface. Basically just masking/disabling wpa_supplicant will make it OK again. I monitored the cpuload and memusage, but I have free memory and the cpu is barely utilized (95% idle). I haven't dug so much into this, I wanted to know if anyone else have experienced anything similiar? Basically the network performance is more or less useless after enabling wifi (installing the drivers & connecting to an AP).

[root at centos-rpi3 ~]# uname -a
Linux centos-rpi3 4.1.19-v7 #1 SMP Tue Mar 15 14:54:48 UTC 2016 armv7l armv7l armv7l GNU/Linux

Currently disabled WiFi:
