ADD: Create doc/experimental/performance_optimizations.md with know how basics on kernel and generally OS level related optimizations.

This is a greate iniciative ( ◡̀_◡́)ᕤ
But--> those optimizations does not apply directly to mtl in a lot of scenarios described

When you get really into it the maximum performance for mtl should be first investigated,

There are a lot of changes here that we suspect will have performance benefits but don't have solid proof and giving them to the clients seem rushed

Also there is a lot of considerations that need to be added

areas of improvement

• queues sizes and their role in limitations for the sessions throughput/amount
• MTL isolation for cores limitations (lcores specified )
• Amount of schedulers per session
• Hyperthreading
• Framebuffer size and its role in input jitter mitigation
• Memory allocation max_memzone argument for big session scenarios
• Numa cores and how to manage the NUMA ram memory throughput
• NIC's limitations and how to find them
• Memory bandwidths
