Looking at the gnuplot output (again, thanks for the gnuplot quick hint :) ), I saw it is capped around 7.26 GiB/s, with block size around 300,000-400,000 (that means 293 - 391 KiB, right?) It's 2.6.36 btw... I think major factor that involve here, but not limited to them, are: - L1/L2/L3 cache size - slab allocator we use - current memory fragmentation level - read ahead size -- regards, Mulyadi Santosa Freelance Linux trainer and consultant blog: the-hydra.blogspot.com training: mulyaditraining.blogspot.com _______________________________________________ Kernelnewbies mailing list Kernelnewbies@xxxxxxxxxxxxxxxxx http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
