   XML firewalls, 70k docs per second?

[ Lists Home | Date Index | Thread Index ]

Network Computing has apparently given kudos to Sarvega and DataPower for XML
security products. Each company has issued a press release citing a report
published by Network Computing. 11 companies were invited to participate in a
round of testing. DataPower, Sarvega and Reactivity accepted.

1. Sarvega: "The Sarvega XML GuardianT Gateway has consistently outperformed the
market in XML Web Services threat mitigation and performance. This leadership is
highlighted by the technology editors of CMP Media LLC's Network Computing in
their XML Firewall Report dated May 3, 2005."

2. DataPower received the Editor's Choice award based on the "XML Threat
Defense" report published in April 28, 2005.

"DataPower(R), the most widely deployed network hardware for securing XML Web
services, announced today that it has won Network Computing's "Well-Connected"
Award for its DataPower XS40 XML Security Gateway(TM) as the leading XML Web
services security solution."

All three of the products tested by Network Computing were 1U or 2U appliances.
They didn't include a parsing and validation XML test as a yardstick to see how
much overhead there was from secure XML processing. For various security-related
tests (encryption, signature verification, LDAP), the DataPower, Reactivity and
Sarvega appliances processed between 300 - 1100 messages per second.

Another competitor (Xambala) has an XPC6050 semantic processor card that it
advertises as the equivalent of 20 Xeon servers. There have been claims it
processes 70,000 XML documents per second (parsing and validation, no security

Has anyone experienced that level of performance with a Xambala card?
