Mon, 01 Apr 2024 17:57:19 +0000

Description:
At SCALE this year Dan Schatzberg and Tejun Heo,
both from Meta, gave back-to-back talks about some
of the performance-engineering work that they do there. Schatzberg presented 
on
the extensible BPF scheduler , which has been
discussed extensively on the kernel mailing list.
Heo presented on IOCost  a control group (cgroup) I/O controller
optimized for solid-state disks (SSDs)  and the benchmark suite that is 
necessary to
make it work well on different models of disk.
