Size Can Matter: Would You Prefer the Hard Drive or the Ramdisk this Evening? Part 3

"In part 1 of this series we looked at the metadata performance when your journal was on a separate disk. Part 2 explored the ramdisk option. Now comes the favorite part of every high school English class: Compare and contrast.

"These tests are not intended as "benchmarks" per se. They are intended more as experiments or explorations to determine how we can influence storage performance by changing options in the file system. This means we are not looking for a "winner" in the comparison. Rather, we are looking for differences or the lack of differences in metadata performance as a function of journal size and journal device to perhaps tell us something about how we can improve performance."
