I'm using aaPanel for almost a month ans i'm really happy with it, even with forum and help support.

My website is online but it's not finished, i'm having a hard time figuring out the best setting for my hardware 1 core 2GB Ram, I have already done alote os tweaks in Ngingx config file and Fastcgi, but I don't know if they are the best for my scenario, thease tweaks were found after alot of web reading regarding to Nginx performance.

So what's the problem or problems?

This al started when I changed from I changed hosting provider dominios.pt from Portugal using the same configuration 1 core and 2GB Ram, managing the same website with cPanel installed with Apache and SSL ### encripted.

Right now i'm at OVHcloud VPS and managing my website with aaPanel installed with Nginx and SSL.

So, what brings me here for help is the fact that my webserver can't deal with many user requests without overloading cpu, but before you, think that the problem is in my webserver hardware, remenber that the older server had the same setup. So itthe problem might be happening because poor conf settings.

With the older hosting company I didn't have these issues but now that i'm basically with the same hardware (maybe better) setup it's happening.

Main problems that i've spent hours to deal with and can't find a way to work this out:

1- Biggest Problem: webserver fails with ssl concurrent connections but it used to work well with http but after changing setings it's worse, mutch worse.

What made me do any of these changes was the fact of Very Poor Performance whith HTTPS, so I tryed to get SSL a+ rating successfuly, it was hard but I did it, already checked Qualys SSL test and immuniweb.com, tryed HSTS preload with errors and a lot of tweaking that was for the worse.

I have an Android Tool that simulates the number os users and it's great to test webserver performamnce, but to be sure I created an account on loader.io (credentials bellow) that you can access to in order to do some testing, I also can give you aaPanel access as well, after reading another issue came up and now I have another problem to solve and is related to HTST preload e redirection.

You can access this link: shorturl.at/kpGY2 to view a folder were a pasted screenshots and nginx conf files and php, all content is editable, so you can see and change for the better.

https://hstspreload.org: This website will shou you whats wrong, I have spend hours trying to fix this but I can't.

The website for testing user connections is: https://loader.io (credentials bellow) it's a free account so only works with my domain https://lovecupid.pt

I also can send you the Android tool .apk (it's free, virus free and straight forward).

So I don't know if you can help me or not, i'm desperate, don't know what to do any more and really tired of this. So I really appreciate if you can have a look and see if you have a little spare time to help me figure this out. Many thanks
