2) Plenty of memory negates most of a filesystems performance concerns.
Whenever you're doing fs benchmarks, work with 2 * RAM worth of data, otherwise you're just benchmarking the cache. ;-)
Yes, Jeff.
The corrolary to which is (what he said): If I have X amount of data and X amount of RAM, and you have Y*512 amount of data and Y amount of RAM, then my filesystem/OS/disk/kernel is better than your filesystem/OS/disk/kernel.
Or, to put it another way: Mine's faster than yours because mine's a red one.
I expect that many (insert name of corporation here) funded benchmarks make very good use of the amount of memory available to disk caches on various systems.
People involved in *serious* network benchmarking, however, first make sure that the cables on their test systems are all the same length. Then they work up from there.
