Considerations for tuning Your Intel® Xeon Linux*/Apache* Server
In this blog, I will discuss a list of useful Linux commands to run, to tune your system for running the Apache web service, as well as some Apache tuning configuration changes which have shown to improve performance in some of our benchmarks. In our tests, we used a software benchmark (SPECweb2009) to simulate load, however the analysis and tuning process described here applies to anyone who is trying to get more performance out of their Linux web servers.
Common Vectorization Tips
Handling user-defined function-calls inside vector-loops
If you want to vectorize a loop that has a user-defined function call, (possibly re-factor the code and) make the function-call a vector-elemental function.Compatibility of Intel® Compiler for OS X* and Xcode*
