  • Using Ruby Fibers for Async I/O: NeverBlock and Revactor

    by Werner Schuster on  Aug 28, 2008 1

    Rails 2.2 is schedule to be thread safe - but will blocking I/O libraries make it necessary to run multiple Ruby instances? We take a look at how non-blocking I/O and Ruby 1.9's Fibers help solve the problem. We talked to Mohammad A. Ali of the NeverBlock project and Tony Arcieri of the Revactor project.

  • Do Java 6 threading optimizations actually work? - Part II

    by Jeroen Borgers on  Jun 27, 2008 3

    Features like biased locking, lock coarsening, lock elision by escape analysis and adaptive spin locking are all designed to increase concurrency by allowing more effective sharing amongst application threads. But do they actually work? In this two part article, Jeroen Borgers explores these features and attempt to answer the performance question with the aid of a single threaded benchmark.
