Nowadays it’s not uncommon to deal with machines with hundreds of GB of RAM. Abundant memory can give PostgreSQL a massive performance boost. However things work slightly different than you may expect. Let’s find out! The problem with the shared_buffer The shared buffer is a segment allocated by PostgreSQL in the server’s memory for managing the flow of data between the data area and the backends. Whether we are reading or changing the data, the database physical pages are stored into share

We at Johnny’s Software Lab LLC are experts in performance. If performance is in any way concern in your software project, feel free to contact us. Copying data can be expensive in some cases, especially since it it doesn’t change the data, it’s just moves it. Therefore we, engineers interested in performance, want to avoid copying data as much as possible. We already talked about avoiding data copying in C++ earlier. In that post, we talked about what mechanism C++ has to offer when it comes

Microsoft used its AI-powered Security Copilot to discover 20 previously unknown vulnerabilities in the GRUB2, U-Boot, and Barebox open-source bootloaders. GRUB2 (GRand Unified Bootloader) is the default boot loader for most Linux distributions, including Ubuntu, while U-Boot and Barebox are commonly used in embedded and IoT devices. Microsoft discovered eleven vulnerabilities in GRUB2, including integer and buffer overflows in filesystem parsers, command flaws, and a side-channel in cryptogra

DeepEP DeepEP is a communication library tailored for Mixture-of-Experts (MoE) and expert parallelism (EP). It provides high-throughput and low-latency all-to-all GPU kernels, which are also as known as MoE dispatch and combine. The library also supports low-precision operations, including FP8. To align with the group-limited gating algorithm proposed in the DeepSeek-V3 paper, DeepEP offers a set of kernels optimized for asymmetric-domain bandwidth forwarding, such as forwarding data from NVLi
