Jak nainstalovat PHP 5.3, 5.4 a 5.5 na absolutně nejnovější Debian 12 a nový hardware ??

Napsal jsem ti přesné řešení tvého problému. Udělej to přes docker kontainer. Nevím co více chceš. Pochybuju, že ti někdo dá 100% návod. Najmi si někoho nebo zapoj mozek….

Kolik ten docker kontainer efektivně využívá procesorových jader ? Umí plně využít 16-jádrový procesor (32 vláken) ?

• By default, a Docker container can use all available CPUs/threads on the host unless you explicitly limit it using options like  --cpus ,  --cpuset-cpus , or  --cpu-shares  when running a container29.
• To ensure your container can use all 32 threads, do not set any CPU limits, or explicitly set  --cpus 32  or  --cpuset-cpus="0-31"  in your  docker run  command29.

• Linux hosts: Docker containers can access all CPU threads unless restricted. You can verify the number of CPUs visible inside the container by running  nproc  or checking  /proc/cpuinfo 9.
• Windows or Docker Desktop (WSL2): By default, Docker Desktop may not allocate all host CPUs to containers. You may need to adjust Docker Desktop settings to allocate more CPUs18. Some users report issues with allocating more CPUs, especially on Windows or WSL2, where Docker might default to fewer CPUs and require manual adjustment1810.

• Docker itself does not limit the number of threads your application can spawn, as long as the container has access to the required CPUs511.
• To fully utilize all 32 threads, your application must be multithreaded or capable of spawning enough worker threads/processes to take advantage of the available CPUs5.

• WSL2 and Windows: There are known limitations in WSL2 (used by Docker Desktop on Windows), such as supporting only up to 64 threads and sometimes only one physical CPU10. If you encounter such limits, check your Docker Desktop settings and WSL2 configuration.
• Resource Limits: Some applications or Docker images may require you to explicitly specify the number of threads at runtime (e.g.,  duplicacy backup -threads 32  for Duplicacy)5.
