Two NX-3500 WAN-optimization devices from Silver Peak Systems performed admirably under testing, and we suspect that 2-year-old Silver Peak will become a major contender in the WAN-optimization market ...

Computer scientists have invented a highly effective, yet incredibly simple, algorithm to decide which items to toss from a web cache to make room for new ones. Computer scientists have invented a ...

The caching of content from disk storage to high-speed memory is a proven technology for reducing read latency and improving application-level performance. The problem with traditional caching, ...

Object caching is an important piece in the design and development of Web portals. In a typical Web portal application, we need the frequently accessed data in a JVM's memory, but, at the same time, ...

Transistors keep getting smaller and smaller, enabling computer chip designers to develop faster computer chips. But no matter how fast the chip gets, moving data from one part of the machine to ...

An SSD can read and write data many times faster than the best mechanical hard drive. On the downside, flash memory is many times more expensive than the innards of a typical hard drive, so ...

For the delivery portion of the overall streaming equation, CDNs use refined content caching and content replication, optimized network paths—including ingress, egress, and midgress data transport—and ...

Before we can do any caching, we need something to cache. Here's a simple DataProvider class that has a couple of expensive operations in its interface: /** * @author adrian at aspectprogrammer.org * ...

Flash storage provides significantly more performance (IOPS and throughput) and lower latency than hard disk-based media. Of course, flash comes with a higher price tag – up to 10 times more than ...
