+1 Significant enough to bump up I think, and we never saw regressions with this size. Please amend the date etc. at the top of the comment too. Here are the results from non x86 worth adding I think: POWER7 3.55GHz, revision 2.1 IBM,8231-E2B 1024=1.3 GB/s 2048=2.5 GB/s 4096=4.8 GB/s 8192=9.2 GB/s 16384=16.8 GB/s 32768=28.0 GB/s 65536=41.4 GB/s 131072=54.8 GB/s 262144=40.0 GB/s 524288=34.5 GB/s 1048576=36.5 GB/s I have access to some NDA architectures and there was an increase in performance seen there also. thanks, Pádraig.
