"Many improvements have been made in the Linux 2.6 kernel to favor enterprise applications. This article presents results from the IBM Linux Technology Center's Web serving testing efforts, comparing the Linux 2.4 and 2.6 kernels from various aspects. The highlights here are the key enhancements in the 2.6 kernel, the test methodologies, and the results of the tests themselves. Bottom line: the 2.6 kernel is much faster than 2.4 for serving Web pages, with no loss in reliability.
"The objective of the Linux Web serving testing effort in the IBM Linux Technology Center (LTC) is to uncover Linux kernel defects. The emphasis is on workloads relevant to real-world enterprise user environments using Web servers/application servers, and on improving Linux kernel stability, scalability, and compatibility with Web servers/application servers. Identification of defects of Web servers and application servers is not the primary focus..."
