I'm typing this on a similar eeePC, a 1001PDX or somesuch with an Intel Atom N455, and those boot times and performance issues would be very anomalous on this machine. The one possible bottleneck I can think of from a hardware point of view would be the processor. To shed some light on this and out of curiosity the output from this command could be interesting:
Code:
inxi -F | head -n 3 | tail -n 2

That rules out the possibility of there being a hardware bottleneck. That's fine in terms of processing guts.

The idea behind running top / htop during periods of lag is to watch for whatever might jump to the top of that list and reveal itself to be squandering resources. Then we would focus on what might be wrong with that process.

The idea behind ureadahead is to identify files which tend to be needed the most at boot and put them into the page cache so they'll be more readily available, with the aim of shortening boot time.

But generally, unless you've encrypted the hard drive (and even then!) or done something else fairly exotic, I'm struggling to think of plausible candidates for inspection to resolve this issue :/

I've noticed that in my last two reboots at the Peppermint splash screen some kind of message regarding my disks appears.
One told me the system was performing a disk-check, with a nice % meter showing the overall progress.
The other time it was just a note telling me there was some kind of problem with the disks, but it disappeared and the system booted without any intervention from my part.

Could this stuff be relevant? :?
