The Linux 2.6.23 kernel has been released today and we have some preliminary benchmarks of the 2.6.23 kernel as we compare it to the past Linux 2.6.22 kernel. We will have more on the Linux 2.6.23 kernel once we have tested it more extensively, but the benchmarks we have ran so far include Quake 4, LAME encoding, Gzip compression, and RAMspeed. If you missed it, among the features for the Linux 2.6.23 kernel include the CFS process scheduler (Completely Fair Scheduler), a variety of virtualization improvements, on-demand read-ahead, and XFS and EXT4 file-system improvements are among the interesting changes.
The hardware we had used for these benchmarks was an ASUS P5E3 Deluxe motherboard, Intel Core 2 Duo E6400 processor, 2GB of OCZ Gold DDR3-1333 memory, 200GB Serial ATA 2.0 hard drive, and NVIDIA GeForce 8600GT 512MB graphics card with the NVIDIA 100.14.19 display driver. The P5E3 Deluxe is backed by Intel's brand new X38 Chipset. The kernel versions used in this very brief comparison were Linux 220.127.116.11 and 2.6.23.
