I also found that people underestimate the importance of L2/3 cache. I'm
compiling very often and it's really faster on my developer's notebook with
4M cache then on faster CPU with 512K. The difference is in the terms of
4-8 times.
I've noticed that there is only 512K cache in the most netbooks which makes
then unsuitable for development. ATM this is stopping me from buying one.
Do you know if there are some with larger cache?

I do not know, but I would guess that it is dependent on the CPU. A
particular ARM or Atom chip may have a particular amount of on-chip cache.
Choosing one's machine carefully would include knowing what type of CPU
is in it.

No specific suggestions. A caution: go to a store and make
sure your future netbook supports ACPI. I've had bad
experiences with my cheap Toshiba Satellite L305 series
laptop: the fan controls (and most other ACPI registers) do
nothing.
It seems either Toshiba or the BIOS maker Insyde H2O has
chosen non-standard SSDT/DSDT table values, with the result
that only Microsoft's OS knows where to twiddle.
There are reports that the omnibook module will correctly
handle Insyde H2O BIOS'ed notebook. Have yet to test here.
Good luck,
Joel

Good point, thanks!
I've compiled one and the same software on my dell d530 and on an eeepc
(don't remember which model exactly, but I think it was atom inside).
Compile time was significantly longer on the latter. So the question is, if
someone knows of a netbook (that is _64bit) and can be used for development
(i.e. has 2gb ram and i.e. 2m cache) this would be exactly perfect for me.
I've tried looking around but gathering exactly this data is kind of hard.
So if someone has a hint, it would be great. Also some of you are dealing
much ofter with hardware than me. Thanks in advance

Just as a Mini Cooper isn't a dragster or a lorry, netbooks are not
*designed* for heavy computational abilities.

maybe this is time for compuserve to come back (I think I have the name
right), used to be able to buy cpu cycles on remove machines - basically
a shell account on a mainframe.
today netbook - connectivity anywhere / take anywhere - but no grunt.
I find with my atom, using syncplaces (a firefox addin), which encrypts
its files - it takes for ever, I am guess i am missing some of those
nice cpu op's that speed these things up.
But my netbook is lite, has loads of connectivity and I can always get
home to the big machine

AMD & Intel's low-power CPUs need encryption engines just like
Via's, and libssl needs hooks into it.

Given the 12" screens and full size laptop keyboards on the current dual
core netbooks I'd hardly call them "netbooks", but rather small laptops, or,
gasp, "sub notebooks". It wasn't all that long ago that the average laptop
had a 12" screen. Given the trend of constant growth and bloat of laptops...
Playing prophet, I predict that in the not too distant future the hw makers
will introduce a "new" class of portable computers called "sub netbooks"
which will start out with the 7" screen that the first "netbooks" were
introduced with, because all the netbooks will have crept up to 10" or 12"
screens.
This industry is famous for taking the old and relabeling it as new in an
attempt to drive revenue, but with almost zero innovation in the "new".

A user's application usage patterns dictate how much memory the machine
needs, not the width of the CPU registers. The comment above belongs in the
winders user world, not here on the debian-user list, where we are assumed
to be competent OPs. The reasoning behind your suggestion is totally flawed.

While Mark's comment is only superficially true, your response is
*really* uncalled for.
For one thing, your first sentence is a /non sequiter/, irrelevant
as to whether a 64-bit system uses more memory than does a 32-bit
system. (Which it does, since the pointers are larger.)
