Ok.. I may get myself in some trouble here... Please be kind..
Red Hat Advanced Server is the first version of Linux to meet all the TPC requirements and provide the performance level of this benchmark.
Numerous open source performance technologies were incorporated, without which, the performance would be significantly below 100,000 tpmC.
The 7x24 - 4-hour response, 3 year SW and HW maintenance is also required.
The TPC audit (done by a certified TPC auditor on-site) requires the demonstration of a full system crash, as well as a single node, without losing a single committed transaction.
The audit for TPC benchmarks take many days...
I hope the Linux community doesn't miss the point that the TPC benchmarks are the toughest benchmarks to run and pass the audit. 138K tpmC will run 95% of the OLTP business environments today. This publication provides input to the many large corporations looking more closely at Linux in the "bet your business" application areas (databases).
Although I agree that the absolute numbers of performance and price/performance may not be applicable directly to many real customer applications, it is a very fair environment (level playing field) to compare HW and SW performance and price/performance.
This, IMHO, is a significant step forward for Linux in the enterprise.
Not cheating... Just using the newer models which were available. It is unlikely that the Windows TPC benchmark could have used 16 - 1.4 GHz front-end clients using IIS to drive the cluster to the max. The Linux clients used Apache (with threads).
It is very hard to do a 1 to 1 comparasion.
The point is... RH Adavanced Server is the first version on Linux which provided this level of performance and could pass all the TPC audit requirements. This is not easy stuff to do...
About 10DB below rocket science;^)
The TPC requires 3 years support to be included in the price. The 24 is 8 Nodes x 3 years.
It is true that the clients are added until saturated. In this case, 2 clients per Linux cluster node was enough to drive the maximum throughput.
The Win2K system required 3 clients (running IIS) to drive the Windows based cluster to the max.
The TPC also requires that the prices published are publicly available (listed on the web, etc.). There is a 17% discount to the hardware and h/w maintenance listed at the bottom of the pricing spreadsheet.
The Oracle software is not available for 6 months. The TPC rules require that the date for the system availablity be the latest date of all the system components, including SW. All the Hardware and OS are available today. In fact, The HP (Compaq) ProLiant DL580 has been shipping for over a year.
