I have ran strace as 'sudo strace apt-get update' and it shows that the
slow-down is really due to abdominal bad kernel I/O performance. Alsmost all
the time is actually spend while blocking on the read() system call (which is
not much of a surprise I guess if we're already looking at kernel versions.. )
Just wanted to do the exercise anyway..
What's the next step? Going backwards indeed to find out when it was introduced?
Is the VirtualBox VM settings "Extended features: Enable PAE/ NX" relevant?
I'm more of an embedded dev so not too familiar with x86 hw
