- by boosting web server performance by eight times, independent research shows -

26 April 2001 - CacheFlow Inc., a provider of content-smart networking solutions, has released independent laboratory test results proving that installing CacheFlow’s cIQ Server Accelerator model SA725 to a web server farm is more effective than adding eight traditional web-servers. The tests were conducted by independent networking consultancy, Miercom.

Laboratory test results:
· Transactions per second increased by 800% (from 13.34 to 105.1)
· Response-times decreased by 87% (0.37085 to 0.04654 seconds)
· The SA725 survived a jolt2 denial-of-service attack
· The SA725 off-loaded SSL transactions from the server, reducing CPU usage from 90.6% to zero.

A CacheFlow customer, Oslo [Stock] Exchanges, recently deployed the SA725 cIQ platform to accelerate high volumes of its web traffic in a recent successful ‘disaster avoidance’ operation. Sidsel Nordhagen, head of IT operations and technical services at Oslo Exchanges said of the research results:

"Often all we have is the claims of vendors on which to base our decisions when buying new technology. Yet our customers cannot afford for us to make mistakes as a result of sometimes over optimistic vendor claims. So it is always reassuring to see independent research, which validates product performance. Miercom’s research shows that we chose well with CacheFlow".

According to Rob Smithers, President of Miercom, “The SA725 proved it boosts Web server performance greatly, by off-loading SSL processing and reducing the latency inherent to Web page retrieval. This SA725 helps alleviate the bottleneck at high volume choke points where many web users are delayed while connecting to the busiest web sites.”

Smithers added ”Our continued testing of the SA725 recently yielded CacheFlow the NetWORKs as Advertised Certification and ‘Recommended Buy” rating. Overall the product performs well with dramatically accelerated web content download, offers excellent redundancy features, and is one of the easiest products to install and manage.”

“Our web site is an essential information channel, so service and availability cannot be compromised,” explained Nordhagen. “CacheFlow’s cIQ Server Accelerator ensures that unexpected peaks in traffic won't cause problems in the future. In a short time it’s proved to be a crucial application for OSE.”

“This independent review proves the value CacheFlow brings to web site owners,” said Nigel Hawthorn, European Marketing Director at CacheFlow. “It shows how many companies are losing out by investing unnecessarily in new web servers – what you might term the weakest link in web operations - instead of increasing the efficiency of their existing infrastructure”.

The CacheFlow cIQ Server Accelerator is the industry’s first family of products specifically engineered for accelerating and scaling high-traffic Web sites. CacheFlow cIQ Server Accelerators are designed to seamlessly integrate with a site's existing systems and networks, delivering an immediate performance improvement for static, secure, and dynamic application content. CacheFlow Server Accelerators can offload up to 95% of web content requests from existing server farms. This can reduce download times by as much as 80%.
