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.

                                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.

                                    Hello. I've noticed recently that Orion is using a lot of RAM. Sometimes, it can use up to 22 GB of RAM with around 15-20 total tabs open which is a lot. For example, when I had two tabs open, (Gmail and Google Docs) Orion used around 6 GB of RAM, while other browsers I tested with those same two tabs used less than 2 GB.

                                    I expect that Orion shouldn't be using as much RAM.

                                    Version 0.99.128.2.1-beta (WebKit 619.1.11.111.2)

                                          FYI I still see high memory usage over time. In this case I had Orion open since ~ Sunday and after finally working through all my windows and tabs, Orion's Memory Used was still 3GB -- with about 2 GB App Memory and 800 MB Compressed.

                                          Here's a snapshot from Activity Monitor with Orion still running but all windows closed:

                                          After I closed Orion, Memory Used went down to 5.57 GB, App Memory down to 2.13 GB, and Compresssed to 855 MB. I also saved a Sample of the Orion process in case that is helpful to share.

                                          While the above summary does not provide quickly reproducible steps, the issue is not intermittent. It does happen to me every time I keep Orion open for a long time. My typical session is ~ dozen windows and ~ 20-something tabs, which I don't think is a lot relative to many other people. I do open and close a lot of windows throughout the day though. If there are additional things to capture next time this happens please let me know.

                                          The usability issue around this is that as Orion's memory usage grows, it's working memory gets pushed into Compressed. Once that happens, Orion feels sluggish until it is restarted. Every "New Window" or "Open Location" is a slight hesitation relative to the snappiness of a fresh session.

                                          Ideally Orion's memory usage after all windows/tabs are closed from a long session would be the same as if it is when it is opened fresh (with no windows/tabs open). I state this as a goal in the sense that its memory usage would be the same during a long session as the equivalent fresh session restoring the previous session (i.e. presumably the minimum for that set of windows/tabs).

                                          I bet Orion snappiness would also be better over long sessions if Orion, or at least its main UI/UX and networking processes and the process for the foreground tab, never spilled into Compressed memory and were last to be swapped to disk out of all its processes. Almost like OS kernels never used to get paged to disk.
