While there is no doubt MS focused on improving file serving performance in the latest
offerings, I would have liked to see the results using XFS instead of ext3. In fairness,
RedHat has chosen ext3 as the default journaling filesystem and they'll have to live with their
choices.

If you read the article and the report, you see all the benchmarks are based on exactly one thing: PEAK throughput. Hrm. If I want to download a 100 MB file, let's review the possible scenarios involved.A) Computer 1 downloads the file at a initial rate of 20 MB/sec for 1 second, then drops to 1 MB/sec for the remainder of the file. Total DL time is 81 seconds, with a peak rate of 20 MB/sec.
B) Computer 2 downloads the file at an initial rate of 8 MB/sec for 1 second, then drops to 4 MB/sec for the remainder of the file. Total DL time is 24 seconds, with a peak rate of 8 MB/sec.
sarcasm=ON
Oh yeah, CLEARLY computer #1 is what you want to buy. Who cares that in the real world, computer #1 took almost 3 times LONGER to actually accomplish the task at hand than did computer #2, when the PEAK rate for computer #1 was 2.5 times FASTER than computer #2?
sarcasm=OFF
Benchmarks without the supporting data (which the testing folks refuse to release) are useless. Only open becnhmarks, with the *complete* raw data, mean anything.

> If you read the article and the report, you see all the benchmarks are based on exactly one thing: PEAK throughput.I was listening to Andrew Tridgells talk from LCA 2003 recently and he mentions this. Samba tries to have a good throughput in all scenarios whereas Microsoft has a peak performance and an exponential falloff as load increases. Some may find it an interesting listen.
