I just had my cell ISP fix their bandwidth problems, and now I get speeds through Spitz that are more inline with my expectations.
However, when I turn on OpenVPN, it drops drastically…like to 5Mbps-^/6Mbps-v from about 20Mbps-^/40Mbps-v.
When I turn off VPN, and turn it on on my laptop only, I get back to the 20Mbps-^/40Mbps-v speeds.
Of course, my laptop has a powerful CPU (i5-8250U CPU @ 1.60GHz) that includes the AES extensions.
Does Spitz’s QCA9533 CPU not have the AES extensions?
I wonder why GL-Inet couldn’t use a Chinese made CPU, eg rockchip RK3128, which seems to have AES. I guess the rockchip has too much other, mostly useless, stuff (eg GPU) which means it comes out more expensive? It’d be good to not be (as) vulnerable to US sanctions and its ‘black list’ as getting chips directly from Qualcomm.
Is there some ‘add-on’ AES accelerator that can be used?
Well, not that I really understand them, but it seems clear to me that they are trying to get h/w aes acceleration to work with OpenVPN - I can’t quite figure out if they’re being successful, or not…and I’m not an expert by any means.
Using Chinese CPU is OK. But those CPU does not has good wifi performance.
Personally, I’d prefer to be unshackled from US companies and have slower performance. Perhaps you should have a ‘US-free product’. It seems like that is the way things are heading for Chinese companies and their products anyway.
