Qualcomm Atheros QCA9565: bluetooth makes wlan slow

I have a Lenovo Y50-70 with a  Qualcomm Atheros QCA9565 as WLAN/BT adapter.
If I connect to WLAN and to my razer orochi at the same times the wlan is unreliable slow and no connection works.
The mouse works. I tried btcoex_enable it didn't helps.
