Re: moving from 3.16-3-486 to 686

2014-11-28 Thread Jörg-Volker Peetz
The answers to your questions depend on what hardware you're using, what kind of
processor, how many RAM. Concerning the CPU, the output of

   cat /proc/cpuinfo

would give some insight.

That kernel's config file has:

# CONFIG_SMP is not set

That means no multiprocessor support (i.e. a single CPU core will be
used all the time regardless of their actual number).

https://en.wikipedia.org/wiki/NX_bit

It's considered a good thing to have one in CPU generally, as
implementing said bit in-kernel will hurt performance.

I see in my latest `full-upgrade' that I've now gone to a 586 kernel:

 uname -r 3.16.0-4-586 

I did nothing purposely to make that happen but there it is.

Does your comment about "multiprocessing/hyp ..." hold true for 586 as
well?

Oh, and what is `NX/XD'?

The -486 kernel lacks support for multiprocessing/hyperthreading and PAE
(which is required for NX/XD bit).

I haven't run into anything I noticed to be a problem related to
kernel version... but not sure I would be able to tell anyway.

My usage is as single user on home lan, light programming, email,
browse net, maybe small lan mail server.

So with that kind of light usage in mind... is there likely to be
anything that 686 offers that I'm likely to need?
Probably makes no difference. You might see a difference if you were 
running heavy image processing or math. What makes a bigger difference 
is the running of 32bit versus 64bit.
