[Astlinux-devel] x86_64 production

Hi Devs,

I personally "upgraded" my main AstLinux box to x86_64, it is a Lanner FW-7541D Atom D525.  So far at "1 day, 16 hours" and 9.5 GB of internet network traffic, no issues.

You can build your own custom image, or the Custom Build Engine http://build.astlinux.org for SVN builds has a new "Architecture: [ x86_64 multi-core ]" option.

For those of you with your own custom builds, no need to rebuild crosstool-ng, just go into your existing ctng-1.20.0-3.2 directory and jump to "## Build x86_64 64-bit toolchain ##" in the crosstool-ng-src/README.


Over the next month or two, before we release AstLinux 1.2.5, we all should think about how to guide users which architecture to use.  Possibly...

1) New installs with 64-bit CPU and 2+ GB RAM use x86_64 ?

2) Virtual machines, since all VM hosts are x86_64, would a x86_64 image run more efficiently ?  or does the somewhat lower memory usage of i586 the deciding factor ?

3) Leave existing installs alone (except for testing) 


For those who want to test x86_64, we put together a WiKi entry for switching an existing i586 system to x86_64...

Attached is a comparison of 2GB RAM AstLinux i586, 2GB RAM AstLinux x86_64 and for reference 1GB RAM Synology Diskstation (x86_64 synology_cedarview_713+) systems.

Most interesting is how the RAM is used.
