Hi Folks, After some gap another BeleniX revision is now available. The following are some of the stuff that goes into this release:
* Upgraded to the OpenSolaris source snapshot: 20060626. * The most important feature of this release is the development of an I/O scheduler for the HSFS module. The I/O scheduler enhances CD/DVD read performance using the following techniques: I/O reordering using the CLOOK algorithm, I/O coalescing, semi- asynchronous readahead for sequential reads. All these techniques together deliver upto 24 second reduction in LiveCD boot time. That apart these enhancements benefit general data CD read performance for a variety of scenarios like install from CD/DVD, playing audio/video files from CD etc. While testing using a patched Solaris Express install DVD, upto 9 min reduction in install time was observed on a fast AMD64 desktop. A detailed write-up with the DTrace profiling results will follow soon. * Updated drivers and device support. * Addressed some bugs and rfes. One bug caused harddisk installs to remain incomplete. * Slight improvement in Xorg startup time by reducing the number of path lookups (and ENOENTs) that Xorg has to do to locate the modules. The workaround was to create symbolic links in /usr/X11/lib/modules/solaris * Introduced a new partition (including extended partitions) viewing tool (/usr/bin/partmgr). It also paves the way for the ability to utilize Linux swap (primary or extended) in future releases. See the website (www.belenix.org) for further details. Regards, Moinak.
