MySQL* Optimization with Intel® C++ Compiler
This article shows how we optimized MySQL using Intel® C++ Compiler and its Interprocedural Optimization (IPO) capability. Without having to modify any code, we compiled the MySQL source code and tested the performance indicators. The result? By using Intel C++ Compiler optimizations on MySQL in a set of test scenarios, performance improved between 5% and 35%―bringing developers another avenue to better MySQL performance.

‘It Can’t Be True.’ Inside the Semiconductor Industry’s Meltdown
“Our first priority has been to have a complete mitigation in place,” said Intel’s Parker. “We’ve delivered a solution.” Some in the cybersecurity community aren’t so sure. Kocher, who helped discover Spectre, thinks this is just the beginning of the industry’s woes. Now that new ways to exploit chips have been exposed, there’ll be more variations and more flaws that will require more patches and mitigation.
"This is just like peeling the lid off the can of worms," he said.
