What OS is the most productive in terms of working with the database/API server?

Question

Operating Systems

Hello.
Which OS is the most productive for running PHP + MySQL, or for running the API server written in PHP, MySQL database and memcached?
Many say that whatever you want - put it like that, the main thing is that you know how to work with it.
I was on Ubuntu, then switched to Debian, they said that Debian is faster and harder to master. But it seems that then they meant about their server, and I have a VDS, where everything is configured by itself.

Answer 1

In these tools, however, the bottleneck will not be the OS - but the software, mysql and php, and the resources that are primarily critical for them.
For mysql, this is the amount of RAM and the performance of the hard disk, and, to the third degree, the processor. For php, the processor comes first, then the RAM, and then everything else.
Again, a lot depends on the scenarios of the application itself and the overall structure of the project.
In short, at your base level, the OS is not so critical in terms of performance, this issue may come up at another stage in the development of the project, and even there it will most likely be a matter of scalability and fault tolerance.

All Linuxes work approximately the same, the question is in tuning the kernel and fs and the ngix muscle PHP settings scripts.
At one time, I tested centos debian ubuntu, the difference in performance is less than one percent on the same software and settings.
