Restartable Sequences "RSEQ" Seeing Up To 16.7x Speedup With Newest Linux Patch
For those making use of Restartable Sequences (RSEQ) on Linux systems, there is an enticing performance optimization on the way.
With work by Mathieu Desnoyers, there is an improvement around cache locality for RSQE concurrency IDs for intermittent workloads. However, intermittent workloads behaving in bursts spaced by more than 100ms on each CPU exhibit bad cache locality and degraded performance compared to purely per-cpu data indexing, because concurrency IDs are allocated over various CPUs and cores, therefore losing cache locality of the associated data." Those interested in this performance optimization work for Restartable Sequences can see this patch for all the details.About The AuthorMichael Larabel is the principal author of Phoronix.com and founded the site in 2004 with a focus on enriching the Linux hardware experience.
