You can see the memory usage increase by 500 MB over that 15 minute period. It will continue to increase.

This is not apparent in your screenshot? The total memory of Orion processes went up maybe 150MB? To make sure this is indeed abnormal, please compare with Safari in same circumstances.

      Vlad I will run the exact same test with Safari and report back. 🙂 The 500 MB increase I pulled from the 'Memory Used' reading in the bottom right corner there. I should have clarified.

          Dustin That is total macos memory usage, orion processes can be added together.

              Safari with the same steps. Open a fresh instance, open the previously mentioned YouTube stream and wait 15 minutes.

              Minute 0:

              Minute 15:

              I hope that's at least somewhat helpful. Again, I will say that 125.6-rc seems to have made a difference with the behaviour I noticed with .5-rc. This latest release is running very well.

                Dustin I interpret your latest set of screenshots that Orion and Safari behavior is roughly the same? (If anything it appears that Orion uses less RAM than Safari?)

                    Yes, it would appear so. Although, there is that strange about:, ... process that appears and takes up a lot of RAM over a period of time.

                    It's not something I can easily recreate as I have no idea what it is or where it comes from. It happens even with just one tab open as you can see.

                      Dustin Thanks for doing the exercise with me. As almost every time before we land on the same conclusion that there is nothing wrong and that Orion is more memory efficient than Safari.

                      I suggest enabling this option in activity monitor so that processes are grouped together.

                          When I group the processes together I add the process name to Activity Monitor so that about:, ... process is definitely Orion but I will enable that setting for future reference.

                              Hi,

                              I am experiencing very high RAM usage with Orion v0.99.127.3-beta, especially with Gmail and Youtube.

                              This image is the RAM usage with two Gmail tabs, and one Youtube tab playing a 30 minute video in Orion, with a clean test profile.

                              This image is the RAM usage with the same tabs opened in Safari.

                              I am aware that even in Safari the RAM usage is pretty high, and therefore this is not a bug report. But I find one Gmail tab consuming 800MB RAM ridiculous, and seeking suggestions on reducing it.

                              v0.99.127.3-beta - macOS 14.0

                              Sonoma (14)

                                Same issue with multiple sites. Especially, youtube/twitch/google drive/reddit/twitter/etc. Happens on a clean profile just by having the tabs open. Some tabs that I've closed still appear in activity monitor.

                                      Hey all

                                      I merged a bunch of 'high RAM usage' posts into this one thread. We would like to get to the bottom of this.

                                      If you are posting about perceived high RAM usage in Orion please follow this procedure to make it useful for us:

                                      • Start a new clean Orion profile
                                      • Note exact steps to reproduce perceived high RAM usage
                                      • Repeat those same steps in Safari

                                      If Orion usage is significantly more than Safari's, post the details here. A video documenting all steps and your methodology would be fantastic.

                                      Thanks!

                                          Vlad Hi Vlad, please find attached to this thread a video showing an easy to reproduce out-of-memory situation with streaming under the latest RC [Version 0.99.127.3.2-rc (WebKit 619.1.11.111.2) / Build date Jun 8 2024] on Mojave. While I don't see the issue with all video streaming with Orion on Mojave, this one is easy to reproduce and I have seen the same issue with this site streaming under more recent macOS, though at least an order of magnitude less significant. I thought this would be a good example since as you can see from the video of my streaming session, my system runs out of memory in less than 10 minutes streaming from this site:
                                          https://www.classicartsshowcase.org/watch-classic-arts-showcase/

                                          This is reproducible everytime with this site. Opening the same site on the same system in Safari (14.1.2) has no issue (it quickly consumes up to a GB of RAM but I can let it stream for hours without issue).

                                          Memory usage really explodes after the 3:50 mark, but I included the video from pre-load through to close so you can the full cycle of the issue. Up until ~ 3:50 you can see memory usage gradually racheting up every 20-30 seconds.

                                          As far as the recording I uploaded, I downsampled it to 540p and 3fps to keep the upload file small. However, I have the original 1080p/60 screen recording if higher framerate or resolution is needed.

                                          If you can't reproduce on your Mojave test system within 10 minutes of streaming that link, let me know.

                                          P.S.I have no idea why macOS's Activity Monitor shows individual process memory usage relatively low the entire time while system Memory and App Usage (and then Compressed) going up constantly.

                                              bzgnyc Please include exact steps to reproduce, including the URL.

                                                  Vlad Basically:

                                                  1. Start with Mojave system (test system is a Mac Mini 2018 w/8GB of RAM running final Mojave release/patches)
                                                  2. Open Orion browser (in the above was running 0.99.127.3.2-rc)
                                                  3. Open link (https://www.classicartsshowcase.org/watch-classic-arts-showcase/)
                                                  4. Hit play
                                                  5. Watch Memory Used/etc rachet up ~ 300MB every 25-30 seconds in Activity Monitor
                                                  6. After 3:50 of streaming, Memory Pressure explodes and it really starts to swap
                                                  7. Letting it continue after that hat will cause macOS to report an low memory situation and suggest killing processes; after that it will start killing processes on its own. I recall it takes ~ 30 minutes to get to that point.
                                                    a month later

                                                    Note just checked with latest RC [Version 0.99.128-rc (WebKit 619.1.11.111.2) / Build date Jul 10 2024] on Mojave and still have same issue.
