A Conversation with Phil Smoot
At every level—failing LUNs (logical unit numbers), failing servers, failing services, failing networks—you want to make sure that all calling services don’t tie up all of their resources on any particular component. And you want to make sure that operationally you can isolate a broken or failing hardware component or server or service from the rest of the network. Most of this experience comes with time. We try to build our bench with folks …

Kelly O’Hair’s Blog: Compilation of JNI Code
… dynamic loading of native libraries can be tricky. Some of the compilation issues relate to the library being loaded into a Java process and causing conflicts in the way the JDK was compiled itself, or the way the JDK assumes code was compiled (sometimes this is considered a JDK bug, but it depends on a great number of factors).
All libraries loaded into java are assumed to be MT-safe (Multi-thread safe). This …

Servlet Performance Report: Comparing Tomcat Performance Across Platforms
Prior to reaching capacity, our Linux server showed it’s ability to scale subtly better, notably with a higher completed response rate. This trend arises again after the servers have been able to recover from their performance slump.
When our servlet found itself hitting memory limits of the app server, the platforms had an opportunity to reveal different error handling techniques. Linux maintained it’s lead over it’s Windows counterpart, except when it was …

Performance Scalability of Data-Mining Workloads in Bioinformatics, from Intel – White Papers, Webcasts, and Case Studies – ITPapers
Data mining is the extraction of hidden predictive information from large data bases. Emerging data mining applications are important factors to drive the architecture of future microprocessors. This paper analyzes the performance scalability on parallel architectures of such applications to understand how to best architect the next generation of microprocessors that will have many CPU cores on chip.
