Chrome for Windows Gets a PGO Speed Boost
The Chromium team has rolled out an update to Chrome for Windows that should bring a big speed boost to the browser. In build 53 for 32-bit and 54 for 64-bit, Chrome now takes advantage of Profile Guided Optimization, or PGO (pronounced Pogo) compiling to give big speed improvements. In their blog post about the update, the team reports that new tabs open 14.8% faster while Page Loads speed up by 5.9%. Not familiar with PGO? It is a compiler optimization technique that is designed to optimize performance. Specifically, Chrome looks at what functions are being used and optimizes those functions to gain the speed improvements. Essentially what it does is move rarely used functions out of memory and frequently used ones into memory.
