As the first loss for the Ubuntu 9.10 series, the OpenMP-based GraphicsMagick performance with the Local Adaptive Thresholding task had regressed by one iteration per minute, or just over 1%.
The SQLite performance has improved dramatically with Ubuntu 9.10! However, this is to no surprise. It's due to Ubuntu 9.04 using the Linux 2.6.28 kernel where as Ubuntu 9.10 is currently tracking Linux 2.6.30 (though hopefully Karmic will end up shipping with Linux 2.6.31). As we discovered when benchmarking the Linux 2.6.24 through 2.6.29 kernels, a nasty regression adversely impacts the SQLite performance in the Linux 2.6.26, 2.6.27, and 2.6.28 kernels. With the affected kernels it takes nearly four times as long to run our SQLite test compared to the pre-2.6.26 and post-2.6.28 kernels.
The simple ray-tracing engine known as C-Ray took slightly longer under Ubuntu 9.10 Alpha 1 than with Ubuntu 9.04, however, the difference was quite small. For those that have not used the Phoronix Test Suite before, tests are run multiple times to ensure accuracy.
