Performance Measured by the Penny
Cloud computing is a game changer for developers. Not because it requires a new architectural model, that is driven as much by fads and fashion as it is by actual hardware requirements. Nor is it the seemingly endless capacity with near-perfect scalability that the cloud is promising. The game changer is how poorly performing code now has a real price in hard currency.

WordPress has Gone Live on Windows Azure
On Tuesday Microsoft announced that Windows Azure would support the LAMP stack, well perhaps “the -AMP stack” is a better term. With Linux out of the picture, Microsoft is courting developers building on top of Apache, MySQL, and PHP/Python including the users of the wildly popular WordPress blogging software.

ORM Profiling Tools for the .NET Platform
Sadly the terms “ORM” and “performance problems” often travel together. By hiding the underlying SQL from the developers, ORMs can offer a huge productivity boost. Unfortunately they also make it easy to generate ridiculously bad queries without realizing it. And without stored procedures to cross reference, finding the offending code without an ORM-specific profiler can be quite tricky.

Beta 2 Brings Refinements to .NET’s Coordination Data Structures Library
Coordination Data Structures (CDS) is designed both to be used directly and to act as the building blocks for more complex concurrency frameworks. It includes advanced synchronization tools like the Barrier, several thread-safe collections, and a couple different ways to create futures.

Google Works on a Protocol Intended to Replace HTTP
Google proposes SPDY, a new application protocol running on top of SSL, a protocol to replace HTTP which is considered to introduce latencies. They have already created a prototype with a web server and an enhanced Chrome browser that supposedly loads web pages twice as fast.

Introducing the Task Parallel Library’s new Cancellation Framework
Task Parallel Library, .NET 4.0’s replacement for ThreadPool, got a face lift for beta 2. In addition to performance improvements, it The most important change is probably the new cancellation framework that replaces parent/child relationships with cancellation tokens that can be freely given to logical groups of tasks.

BERT as Dynamic Alternative to Protocol Buffers/Thrift
Google's ProtocolBuffers and Facebook's Thrift are options for binary serialization, but not ones that pleased the GitHub team - so they created BERT/BERT-RPC based on the Erlang's 'external term format'. BERT/BERT-RPC now power parts of Github's internal communication.

The DLR’s Adaptive Compiler
The Dynamic Language Runtime has significant performance improvements over traditional interpreters for Python and Ruby, once it is warned up. But for code you only use once or twice, the performance can be downright pitiful. Fortunately a solution is in sight.

SPEC for SOA
Until recently there was no standardized way in which to measure the performance of SOA infrastructures, such as ESBs. Now the Spec Organization have announced that they are working with vendors to define just such a benchmark.
