Leif Hedstrom updated TS-4719:
------------------------------
Backport to Version: 6.2.1
> Should have NUMA affinity for disk threads (AIO threads)
> --------------------------------------------------------
>
> Key: TS-4719
> URL: https://issues.apache.org/jira/browse/TS-4719
> Project: Traffic Server
> Issue Type: Improvement
> Components: Cache, Core
> Reporter: Leif Hedstrom
> Fix For: 7.0.0
>
>
> We should properly interleave AIO threads (disk threads) evenly across the
> NUMA nodes, and have affinity on those nodes. That would allow for better
> memory distribution across NUMA nodes. I've noticed pretty uneven allocations
> on some boxes, which I attribute to this problem (but no strong evidence, but
> it does make sense).
