Some people think that phoronix benchmarks are not very serious/reliable/meaningful, but i thought it'd be better to post false warnings than letting real regressions slip in without notice. The regressions would be: - 7zip MIPS ("7zr b" command) http://www.phoronix.com/data/img/results/linux_2630/1.png - tiobench latency (not throughput) using 64MB writes with 32 threads http://www.phoronix.com/data/img/results/linux_2630/7.png -gnupg 2GB file encryption http://www.phoronix.com/data/img/results/linux_2630/3.png Full article: http://www.phoronix.com/scan.php?page=article&item=linux_2630
