We discussed the methodology in the first part of the article; in this one, we are testing HTTPS in more realistic scenarios. A Let’s Encrypt certificate was obtained for testing, and Brotli compression was enabled at level 11. This time, we will attempt to reproduce a scenario for deploying a server on a VDS or as a virtual machine on a host with a typical processor. To accomplish this, we set a limit of: […]
Hello, Habr! In this material, we will discuss whether it is worth organizing RAID arrays based on solid-state SATA SSD and NVMe SSD solutions, and whether there will be any significant profit from this. We decided to delve into this issue by examining the types of controllers that allow this, as well as the applications for such configurations. One way or another, each of us […]
