minimize mbox mdbox fragmentation
...benefit from such a change as well. I was having a discussion on the XFS list about this, trying to tweak XFS mount options to mitigate the fragmentation effects. Alas, there is no way to do this purely at the filesystem level. From Dave Chinner, one of the lead XFS devs: "What you want is _physical_ preallocation, not speculative preallocation. i.e. look up XFS_IOC_RESVSP or FIEMAP so your application does _permanent_ preallocate past EOF. Alternatively, the filesystem will avoid the truncation on close() if the file has the APPEND attribute set and the application is writing via O_APPEND......

Samba as a Multiple Domain Controller on a complex setup
...and an administrator at domain2 but with no access at all to domain3 c. All of these users and domains will reside on the same, single machine d. The LAN is segmentated into 3 different IP networks, but they all share the same 'cable' e. The LAN(s) and the Samba DC are in different _physical_ networks, with a Linux router/fw in between them, that also gives access to the Internet link and to an external VPN. So network logons into the Samba Server must work across subnets. (Internet link) | e...

[OT] Memory Models and Multi/Virtual-Cores -- WAS: 4.0 -> 4.1 update failing
...itions passes-the-buck decently in lieu of a complete core redesign (which they haven't done since 1994). But the concept of extending the pipes any further for performance has been largely broken in the P4, and Intel is actually falling back to its last rev of the i686 original, P3. Multiple, _physical_ cores have been the first step. This is little more than slapping in a second set of all the non-SRAM transistors, plus any additional bridging logic, if necessary. AMD HyperTransport requires none -- as HyperTransport can "tunnel" anything, EV6 memory/addressing, I/O tunnels/bridges, i...
