- ForHackernews 9y agoIt used to not be paywalled: > Measureable: 8-12% - Highly cached random memory, with buffered I/O, OLTP database workloads, and benchmarks with high kernel-to-user space transitions are impacted between 8-12%. Examples include Oracle OLTP (tpm), MariaBD (sysbench), Postgres(pgbench), netperf (< 256 byte), fio (random IO to NvME). > Modest: 3-7% - Database analytics, Decision Support System (DSS), and Java VMs are impacted less than the “Measureable” category. These applications may have significant sequential disk or network traffic, but kernel/device drivers are able to aggregate requests to moderate level of kernel-to-user transitions. Examples include SPECjbb2005 w/ucode and SQLserver, and MongoDB.
- ghaff 9y agoSorry about that. I confirmed earlier that I could get to it from an incognito window. The sibling post has a relevant excerpt. I’ll look into. [ADDED: It's back. Was pulled back to make some changes.]
