Hello Marco,

But my question is: why if I use a Windows based RDP server it's working without problems and if I do (almost) the same in Power Linux we got performance problems specifically in the browser?
You connect with RDP to a Linux graphical screen, do I understand right? So, there may be two culprits:
- Microsoft most likely did heavy optimizations on the server side to make RDP as fast as we know it. I never would expect that connecting with RDP to a X-Server session would provide the same performance. I was tinkering with that stuff a few years ago, because using remote X protocol in Windows is/was always requiring requiring additional software.
- I suspect that Linux Browsers are also heavily optimized for x86 code. Maybe some critical routines have been carefully crafted in assembler to provide the pest performance, while POWER is a niche, compared to the overwhelming usage count of x86. I did not dig into the gigantic blob of Firefox Code to look, though.
Why we guest users in an RDP session? Because we can decide the browser and the update level of the browser. We see many ugly things letting people choose whatever they want to run our ERP.
I don't know any details yet but to me this sounds like a basic architectural problem in the ERP itself. For years, browsers have become more and more similar in behaviour, especially after the release of the HTML5 standard.
Maybe you could set up a similar Linux terminal server on an x86 server or VM to test performance with this one?
