I'm just wondering what folks are using to benchmark/tune large arrays these days. I've always used bonnie with file sizes 2-3 times physical RAM. Maybe there's a better way?
Depends on your needs. You want to simulate as close as possible your intended application.
A lot of the commonly used tests such as bonnie/bonnie++ proved inappropriate when you want sync behaviour. I don't know about now but bonnie did not do fsync calls and so performance was better with it than real world performance for cases where fsync was used in the application.
