Previously the majority of the VM was under a single token, the vm_token; now vm_objects (mappable entities) are each under a private token, concurrent page faults in the same object can proceed, and VM SMP scalability overall improved. Results for Postgres and MySQL, among others, are excellent. +Francois Tigeot [worked on benchmarks](http://leaf.dragonflybsd.org/mailarchive/kernel/2011-11/msg00004.html) comparing DragonFly 2.10 and DragonFly 2.13, among other operating systems. The [resulting graphs](http://dl.wolfpond.org/Pg-benchmarks.pdf) show how well DragonFly responds to multiple CPUs. (2.13 is the version of DragonFly that became 3.0.) See: -http://leaf.dragonflybsd.org/mailarchive/kernel/2011-11/msg00004.html -http://dl.wolfpond.org/Pg-benchmarks.pdf -### HAMMER performance greatly increased -A new time domain multiplexing method has been added to balance storage operation types over long time periods. As a result, HAMMER performance increased by XX% under some typical scenarios (see benchmarks here, here, here) and HAMMER fairness and throughput under heavy storage loads is now better than all tested alternatives. +### HAMMER performance greatly increased -http://leaf.dragonflybsd.org/mailarchive/commits/2011-07/msg00086.html +A new [time domain multiplexing method](http://leaf.dragonflybsd.org/mailarchive/commits/2011-07/msg00086.html) has been added to balance storage operation types over long time periods.
