![]() If I decrease the values any lower than this I cannot get the app to start.Ĩ3ccc9b2156d: Mem Usage: 70.36MiB / 72MiB | Mem Percentage: 97.72%Īnd here you can see a breakdown of all the native and java heap memory on exit. Here is an example of docker stats running a very simple Spring Boot application with the above limits and with the docker -m 72m argument. threads = 1 This will limit the number of HTTP request handler threads to 1 (default is 200) In addition to the above JVM options you can also use the following property inside your application.properties file: With -XX:MaxRAM=72m This will restrict the JVM's calculations for the heap and non heap managed memory to be within the limits of this value. With -Xss512k This will limit each threads stack memory to 512KB instead of the default 1MB With -XX:+UseSerialGC This will perform garbage collection inline with the thread allocating the heap memory instead of a dedicated GC thread(s) You can get a simple Spring Boot app down to around 72M total by using the following JVM options. Throw in Spring Data REST, Spring Security and a few JPA entities and you'll be looking at 200M-300M minimum. The bare minimum you'll get away with is around 72M total memory on the simplest of Spring Boot applications with a single controller and embedded Tomcat. The following images show examples of views in Task Manager when system memory usage is abnormally high.Little late to the game here, but I suffered the same issue with a containerised Spring Boot application on Docker. ![]() Sustained memory usage of 90% could mean Teams isn't giving memory back to the system, which indicates a problem. With this amount of memory usage, Teams should be giving memory back to other apps and workloads. Sustained overall system memory usage of 90% or higher across all apps.Slow system performance or applications hanging.High memory use when multiple large applications are running simultaneously.If you see one or more of the following symptoms on your computer, you could have a serious system memory issue: In systems where memory is scarce, Teams will use less. When computers have more memory, Teams will use that memory. Each of the systems is processing similar workloads (same apps open and running). The following graph depicts memory usage by Teams on four separate systems, each with different amounts of memory available. In this way, similar Chromium workloads can utilize varying amounts of memory, depending on the amount of system memory that is available. Chromium tunes Teams memory usage on an ongoing basis in order to optimize Teams performance without impacting anything else currently running. When other apps or services require system memory, Chromium gives up memory to those processes. Whether you're running the Teams desktop app or the Teams web app, Chromium detects how much system memory is available and utilizes enough of that memory to optimize the rendering experience. It is important to understand the expected behavior of Teams when it comes to system memory, and to know the symptoms of truly problematic system memory issues. The following image shows side-by-side memory usages of the Teams desktop app for Windows and the Teams Web app (in this example, running in Google Chrome). See Chromium Memory Usage and Key Concepts in Chrome Memory for more information. More information about Electron is available at their Web site. ![]() Both the web app and the desktop versions use memory in a similar way to how a browser would use it. Another advantage of this architecture is there's a similar memory usage profile between the Teams web app and the desktop version. This parity is possible because Electron and Chromium maintain a similar code base across all versions. Teams being designed on Electron allows for faster development, and it also maintains parity between Teams versions across different operating systems (Windows and Mac). This is the same rendering engine behind many of today's most popular browsers, including Edge and Chrome. To achieve this, the Teams desktop client was developed on Electron, which uses Chromium for rendering. Teams is designed to use modern web technology. This article describes how memory is used by Teams, and why the Teams desktop application (app) and the Teams web app do not prevent other apps and workloads on the same computer from having enough memory to run optimally. Some Microsoft Teams users have questions about how Teams uses memory.
