Hello,

I also did several tests on the 4.19 ipq806x (NBG6817). I noticed that VPN 
throuput (IPsec Performance) dropped to 30% with exactly the same config 
(kernel and openwrt), kernel crypto and arm crypto
stuff tested.
Also the whole system feels a bit slowier. Timers (clock, ddr) in dts have been 
compared, also checked in the running system. I'm a fan of 419, but this needs 
be solved before and I have no clue where
to look. Any ideas?

Kind regards,

André
