Hummingbird vs Eddy vs Tunnelblick vs OpenWRT

[Moat 11]

Hello,

CHACHA20 is being rolled out. I would like to know how to best upgrade my system to improve performance.

OPENWRT
I use AirVPN on OpenWRT powered routers which do not have AES-NI.
Apparently CHACHA20 and OpenVPN 2.5 are supposed to be in OpenWRT ?
But officially OpenVPN in OpenWRT is at 2.4.7-2 ?

Is there a specific library or package I need for OpenWRT to run AirVPN CHACHA20 ?
What is the to be expected performance boost switching to AirVPN's CHACHA20 on an OpenWRT router without AES-NI ?

APPS
I also use AirVPN on mac through Tunnelblick. Tunnelblick stable supports OpenVPN 2.5 Beta 3. Tunnelblick latest beta supports OpenVPN 2.5

Can Tunnelblick do AirVPN CHACHA20 ?
What is the speed difference using AirVPN CHACHA20 through Hummingbird, Eddy and Tunnelblick on a mac Intel Core i5 AES-NI chip ?
What is the influence on battery/power drain using AirVPN CHACHA20 through Hummingbird, Eddy and Tunnelblick on a mac Intel Core i5 AES-NI chip ?

Thanks.

19.07.4 was released a month ago. At release time OpenVPN 2.5 was still a release candidate, so there's a plausible reason why it's still on 2.4.7 now.

If it's running some variant of OpenVPN 2.5, be it a beta or RC, most probably yes.
And as Staff wrote on multiple occasions, it usually doesn't improve throughput on machines with AES-NI-capable CPUs (sometimes it's even worse). However, it does improve on ARM/MIPS/non-AES-NI CPUs, in some cases by quite a lot. To know for sure how much it will improve for you you must do some tests yourself once all servers are updated, which will happen during the next week.
