We had 4GB of RAM in our nodes, so this was a good discovery. Changing the benchmark size down to a couple of hundred megabytes did not seem to affect the results at all, just the amount of time it took to get them. The settings for the read-ahead and write-behind translators greatly affect the times for the random access benchmarks. ~~Sam
