[ubuntu-uk] Dual-Core = less not more?

[Ian Pascoe]

Matt

I'm surprised that a dual processor machine came with only 1 Gb of RAM - I
thought it was more common these days to ship with 1 Gb of Ram per
processor.

However, the differences between multi core and multi processor are rather
ambiguous as depending on the manufacturer they can mean the same thing!
Generally speaking multi core processors share the same DIN whereas multi
processors each have their own seperate socket.

But, as long as things work, thats great - just bear in mind what Chris says
about the fact that unless you are running multiple processes / apps, you
won't generally see much of a difference in performance in apps, as,
referring back to a pre Xmas posting, very few apps on Linux are multi
threading yet.

    Hi all,

    I was one of the many who purchased the Dell laptops when they shipped
    here in the UK with Ubuntu pre-installed.  I've got a Pentium Dual-Core
    chip (not a core-duo although I'm not sure what the difference is!)
    installed and although /proc/cpuinfo shows both cores as seperate
    processors, I'm really not convinced that the dual-core with 1024MB RAM
    is faster than my old 1.4GHz with 512MB RAM.

    I've got stock Gutsy installed on the laptop (upgraded from feisty using
    apt-get dist-upgrade) so if there are any packages that you think would
    be more beneficial, please let me know.

    One of the things I've stumbled upon in the forums is the possibility of
    running x64 on Core2-Duo processors - would that help me here?

    Cheers,

    Matt.

  I think there is a point where the performance just levels out. You will
notice the difference when you run lots of apps at once. I dont know, but
I'm running X86 on a 2x dual xeon machine with 8gb of ram, and it boots
about the same time as my dual core 3.6ghz 2gb ram, but is much better on
performance, when running say, lots of applications, database stuff etc..
