Our tests of a hyperthreading-enabled Intel Xeon DP server showed, on average, a 45.71 percent increase in SQL transaction performance and a 31.13 percent increase in three-tier Web application performance, versus the same system with hyperthreading disabled.

It doesn't seem right for them to just disable hyperthreading for the comparison system. Who knows what performance penalty that gives to a core that is designed to be hyperthreading.

Also, it does look like these people have the objective of making the Xeon look good, which devalues their results. For example, their "averages" are taken over a range of number of connected users, yet the benefit of hyperthreading decreases with more users. Why on earth do this averaging? It is the benefits to a more heavily loaded system that are more relevant, so why include the 60% benefit for 15 clients, when it goes down to 34% for 50 clients? If the server only has 15 clients connected then you are not exactly worried about its performance are you?

And why do they stop at 50 clients for the database test? I would expect the numbers for 75 and 100 clients to be equally interesting/significant.
