Re: moving from 3.16-3-486 to 686
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. -- Regards, jvp. -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".

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). > Oh, and what is `NX/XD'? 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'? -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".

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. -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
