In my previous post, I presented some startup timings with syzygy-optimized Firefox binaries. People asked whether those timings were on my work laptop (quad-core i7, Windows 7, SSD) and I confirmed they were. Since those timings were encouraging, but not overwhelming, folks suggested that I might try timing things on a more conventional system.
