The following code writes a 16×16 bitmap to a framebuffer using up to AVX2 instuctions. I’m sure it can be improved with AVX512 but I’m only interested in improvements using AVX2 and below. Specifically, I want to know if there is a more efficient way of doing it. Each bit in the bitmap represents aRead more

I needed a simple way to run tests on the last n bytes of data received from a socket, and a ring buffer seemed to be the most efficient way to handle it. This is a very basic buffer that stores integers and has an accessible snapshot of its contents as a String for quickRead more

Been searching but no clear understand. TDE encrypts at rest not in flight. But does in flight refer to only between server and client or also between server and SAN storage. When a database uses TDE, does a page, when it is written to the disk, leave the buffer pool encrypted. So if somebody wereRead more

i tried to find some values but only what i found was for PLE < (buffersize *4)/300 but nothing for Page write sec. As i assume it depends on memory somehow. Thanks for answers 🙂Read more

I work a lot with byte buffers and have to extract different parts. In this example, it’s 4 byte, but it ranges from a single bit to 128 bit. Speed is the most important metric here. See the code for a MWE. I’d like to know if there is a better way. #include <stdint.h> staticRead more

I need to send a large data between the WCF(netNamedPipe) and the client. My interface is decorated with SessionMode = SessionMode.Required so i can’t change the tranferMode to streamed. After some seconds of processing the proxy status became Faulted. How to deal with that problem ? Can i reset the buffer when the max sizeRead more

Всем привет! Вызываю следующую функцию: void leftDirectBytesShift (std::byte* head, const std::byte* end, std::byte* newHead) noexcept { if (head >= end || newHead < head || newHead >= end) { return; } std::byte* next = newHead; while (head != next) { std::byte* temp = head++; *temp = *next++; if (head == newHead) { newHead = next;Read more

One of the Postgres process is using memory which is more than shared buffers. Can anyone explain why it is happening and how to solve this. In our server, shared_buffer = 24 MB, but Postgres process is using 79 MB. Operating system: Ubuntu 12.04 LTS RAM = 8 GBRead more

Previously I had asked for help implementing a standard-compliant container and corresponding iterator implementing the gap-buffer algorithm for efficient text editing. Thanks to the feedback I got, it now works swimmingly or so I thought. Now I want to implement some more advanced features than simple insert and delete for which I need to, givenRead more
