[SOLVED] TSC on Atom CPU and downscaling CPU frequency

[agent_kith]

So will putty work or does it have to be vnc. I seem to be having a lot of trouble with vnc. I think its a network issue. 

It can be done via VNC if you want the graphical environment. Or better yet as a commandline, with the output to be loaded later.

 

Look forward to trying that

Hopefully will build that in the coming days. For 1000 Hz kernels to work well, you really need a computer with a very fast CPU. Let's say a computer can execute X instructions every second. A 100 Hz timer means a timeslice of X/100. And a 1000 Hz timer a timeslice of X/1000.

Definition of time slice is:

Code:

The period of time for which a process is allowed to run in a preemptive multitasking system is generally called the time slice or quantum. The scheduler is run once every time slice to choose the next process to run. The length of each time slice can be critical to balancing system performance vs process responsiveness - if the time slice is too short then the scheduler will consume too much processing time, but if the time slice is too long, processes will take longer to respond to input.

An interrupt is scheduled to allow the operating system kernel to switch between processes when their time slices expire, effectively allowing the processor’s time to be shared between a number of tasks, giving the illusion that it is dealing with these tasks in parallel (simultaneously). The operating system which controls such a design is called a multi-tasking system.

So when you are using a slow processor like an atom, running a high timer is going to be detrimental in theory. Basically the more process you set to execute in RT, potentially the worse the latency jitter will be.

This will only be evident when the software is poorly written. I don't think Squeezelite or MPD will fare worse, but can't vouch for the other players.

 

I notice there are multiple squeezlites , is it just feature differences or sq also. Is there a comparison thread somewhere

Not really.

Multiple versions is just that, multiple versions. e.g. if you have been listening to a version of Squeezelite for a long time, you may not want to change to the latest version. This is just a technique to reduce the number of variables when auditioning music. In my case, Squeezelite 1.6.4 is my 'control'. When testing new updates to Squeezelite, it's audio qualities is judged against the control.

Same with MPD. The control is v17, and all other versions of MPD is judged against it.

Frankly speaking though, you need to be very familiar with the track, and know what cues to listen to for a particular track. Without these cues all these different player versions will sound the same after a while.

Unless you're really serious about critical listening, don't think too much into it and just use the latest version, or the version that gives you the best features.


 

Ok, I am pretty sure a.dent still uses Roon with HQ player but will follow up
