• Joyent builds high performance SmartOS instances that
frequently beat Linux, but that's due to more than just the OS.
• Conﬁg: OS virtualization (Zones), all instances on ZFS
• Hardware: 10 GbE networks, plenty of DRAM for the ARC
• Analysis: DTrace to quickly root-cause issues and tune
• With SmartOS (ZFS, DTrace, Zones, KVM) conﬁgured for
performance, and with some analysis, I expect to win most
head-to-head performance comparisons
