Last week PostgreSQL merged support for IO_uring that can provide for "considerably faster" performance of this popular open-source database server. Over the weekend some additional improvements were merged to the asynchronous I/O "AIO" code to PostgreSQL, including introducing a new batch mode that can also provide a performance win...

Cloud Hypervisor began as an open-source Intel software project more than a half-decade ago with an emphasis on security and cloud deployments while leveraging the Rust programming language. With time its scope has broadened a lot as has its industry adoption. With time it added ARM64 support and recruited AMD, Ampere Computing, Microsoft, and others as its supporters while being folded into the Linux Foundation. The latest expansion for the project is introducing experimental RISC-V 64-bit support...
