| Linux Release Details: |
| BeleniX 0.4.4 has been released now |
| This release marks one more important step for live CD performance. After a couple of months of hacking and testing, this release includes an enhancement to the HSFS filesystem module that improves CD-ROM access time by up to 30%. In addition, a bunch of work is going around packaging so the next major release should be complete with packaging based on Pkgsrc." |
About the BeleniX 0.4.4
BeleniX is an OpenSolaris distribution which is currently a LiveCD (runs directly off the CD). It includes all the features of OpenSolaris and adds a whole variety of opensource packages. It can be installed to harddisk as well.
Some More Detail
The significant feature of this release is the development of an I/O scheduler for the HSFS module in OpenSolaris. The HSFS (High Sierra FileSystem) module is responsible for reading from data CDs. The I/O scheduler enhances CDROM read performance by using the following techniques: I/O reordering using the CLOOK algorithm, I/O coalescing that groups together multiple I/O requests into one, semi-asynchronous readahead that greatly benefits sequential access. A detailed technical write-up will be put-up soon. This HSFS enhancement reduces LiveCD boot time by upto 24 seconds.
The CDROM performance enhancement is not only meant for a LiveCD scenario. In fact it benefits general data CD and DVD access greatly like playing audio/video files and install from CD. In tests using a patched Solaris Express installer DVD, the enhancements have provided a 22% reduction in install time.
Updated to a recent OpenSolaris source snapshot(20060626, 26 Jun 200) that contains many fixes and improvements to core OpenSolaris.
