Late yesterday we released build 110 of the OpenSolaris distro, see [osol-announce] OpenSolaris development package repository build 110, x86/x64/SPARC
for the particulars.
Since I was traveling and missed posting a note about build 109, it's probably a good idea to mention one of the changes that appeared there and continues with 110: going to only a single, global CD image. This had been our intention all along since starting the distribution, but it depended on the LZMA (de)compression support in lofi; we got that done before the 2008.05 release, but its performance was judged to be too slow at the time so we made the expedient decision to ship two different CD's, with the primary CD using the better-performing gzip algorithm. We figured we'd come back to that issue once we got the LZMA code integrated into the ON gate, which just finally happened a couple of weeks ago.
In the meantime, OpenSolaris community member (and super-contributor!) Juergen Keil took an interest in the performance issue, and found the primary culprit in the lofi code, which was repeated decompression of the same data (see bug 1119
for the discussion if you're curious). The performance improvement is, we believe, good enough to return to just the single image for the next release. But we would like data to confirm that, so if you do an install from the build 109 or 110 CD, please send info on the time it took (you can just send the installation log if you like; it's found at /var/sadm/system/logs/install_log after installation) and the basic stats on your hardware (processor speed and number of cores, memory size) to firstname.lastname@example.org
, we'd appreciate it.
