Tarari Releases Five XML Performance Benchmarks; Extreme Acceleration Obtainable with RAX 4 for XML Schema Validation, XML Content-Based Routing, XML Publish-Subscribe, Federated Identity Management/SAML, and Binary XML.

LAS VEGAS -- Tarari Inc., the award-winning acceleration company, announced today the immediate availability of five XML RAX 4 performance benchmarks documenting the extreme acceleration obtained for XML Schema validation, XML Content-Based routing, XML Publish-Subscribe, Federated Identity Management/SAML, and Binary XML. Tarari makes Content Processors based on ASIC and production board technologies that OEMs and developers can simply plug into their networking devices, appliances and servers to accelerate and offload content processing. Tarari will demonstrate RAX 4 in Booth 566 at Interop in Las Vegas, May 3 - 5, 2005.

"As developers have attempted to scale their XML applications and Web Services deployments, they have encountered what many consider an XML performance crisis," said Randy Smerik, president and CEO, Tarari Inc. "Some pundits have gone as far as suggesting that poor XML performance threatens the viability of Web Services. With Tarari acceleration technology, the major barrier to ubiquitous Web Services has been smashed, and developers can easily and cost-effectively put their projects back on track."

1) XML Schema Validation

XML Schema Validation, critical to guaranteeing security and message integrity in Web Services, is a notoriously CPU-intensive process that has been a major impediment to widespread deployment of Web Services-based transactional systems. The Tarari study documents that with the addition of a Tarari RAX 4 PCI-X card, a single dual 2.8 Ghz Xeon appliance performed at over 11,000 full XML Schema validations per second on SOAP messages and attained one gigabit per second throughput.

2) XML Content-Based Routing

XML content-based routing is an "intelligent network" paradigm enabling routing decisions based on a dynamic analysis of document content. Prior to RAX 4, no XML engine had sufficient power to allow such content-based routing decisions to take place at wire speed. The Tarari study documents that with the addition of a Tarari RAX 4 PCI-X card, content-based routing on a single dual 2.8 Ghz Xeon appliance was accelerated by 200 times and throughput rates reached more than 10,000 messages per second.

3) XML Publish-Subscribe

XML Publish-Subscribe is a key technology in the red-hot area of event-driven, real-time business information architectures. The low power of XML engines, however, have restricted implementations to topic- and keyword-driven approaches that force publisher and subscriber to be coupled, preventing the full realization of the Web Services vision of a dynamic services marketplace. The Tarari study documents that a completely decoupled, dynamic architecture can be implemented using Tarari's PubSub RAX 4 module. Performance data from this study shows that despite the more flexible architecture, 25 million subscription fulfillments per second can be achieved.

4) Federated Identity Management/SAML

Security Assertion Markup Language (SAML) is the core XML technology required for Web Services federated identity management, enabling secure trading among business partners and between consumers and businesses. Federated identity management requires evaluation of a multitude of security assertions and credentials and, once again, poor XML performance is a threat to realizing the vision of open yet secure Web Services. The Tarari study documents how RAX 4 was used to accelerate SAML processing between 40 and 70 times the rate at which SAML assertions can be processed by XML software.

5) Binary XML

The World Wide Web Consortium (W3C) and many companies are looking at a binary recoding of verbose text XML in order to reduce bandwidth consumption and increase processing speed. The Tarari study demonstrates that improvements can be realized in both areas using RAX 4 with Tarari's hardware-based standard ZLib compression. The hardware-based compression reduced XML document size by up to 97 percent. With hardware-based acceleration, the performance impact of compression and decompression and XML processing were reduced to negligible levels. The study also describes the use of RAX 4 to produce random access index information which, when included in the binary package, can completely eliminate parsing cost incurred by the message consumer.

The Tarari study documents complete message processing throughput of 1.6 Gbps and 60 times acceleration compared to text XML processing. This improvement does not consider the additional savings in the network from a 97 percent reduction in message size.
