The ETA project at Intel Research and Development has developed a software prototype that uses one of the Intel® Xeon processors in a multi-processor server as a packet processing engine. The prototype is used as a vehicle for empirical measurement and analysis of a highly programmable packet processing engine that is closely tied to the server’s core CPU(More)
The boundary between the network edge and the front-end servers of the data center is blurring. Appliance vendors are flooding the market with new capabilities, while switch/router vendors scramble to add these services to their traditional transport services. The result of this competition is a set of ad-hoc technologies and capabilities to provide(More)
Detailed measurements and analyses for the Linux-2.4 TCP stack on current adapters and processors are presented. We describe the impact of CPU scaling and memory bus loading on TCP performance. As CPU speeds outstrip I/O and memory speeds, many generally accepted notions of TCP performance begin to unravel. In-depth examinations and explanations of(More)
A 19-yr-old man had features of chronic hepatitis with piecemeal necrosis as the sole clinical feature of the idiopathic hypereosinophilic syndrome. Liver biopsy specimens demonstrated the presence of activated eosinophils and, by immunohistochemical staining, major basic protein in areas of hepatic cell damage. The case demonstrates the clinical(More)
High-performance solid state disks (SSDs) deliver a 2–3 orders of magnitude increase in I/O operations per second (IOPS) over hard disk drives (HDDs). Extreme-performance SSDs can produce up to 120,000 IOPS for random-access reads, taking as few as eight direct-attached SSDs to reach one million IOPS. However, today’s multi-core platforms have long been(More)
The ability to provide diagnostic information for workload performance is of great value in the performance tuning process. Not only can it orient the tuning process by identifying key performance issues, it can also be used to estimate the severity of each performance issue and the potential gain from addressing it. This work investigates the ability of(More)
