Venkatesh Srinivas has been working on new version of DragonFly’s malloc; he’s published an extensive writeup (which is inexplicably split in two in the mail archives) that includes several of my favorite thing: graphs! For those short on attention: the new malloc has around a 20-25% improvement over the existing malloc in MySQL sysbench results.
A running description of activity related to DragonFly BSD.
But overall results are still very low :/
Next up: background thread malloc?
It almost seems feasible.
