    Just about every show I try to watch when I'm on the page of the video my CPU usage goes up to max. Tried on multiple browsers and its the same. Each browser also reports blocked content that is unsafe. Browsing through the shows is fine its only when its on a page with the video so I'm guessing it may be from whoever the mirror is from. Shows it happens on for me are That Time I Got Reincarnated as a Slime, Goblin Slayer, Death March to the Parallel world as well as others I randomly clicked on.

    Sorry but forgot info, I tried Chrome and Edge, OS is windows 10.

    Doing more debugging to help out. I tried going to the download section for one of the anime (that time I got reincarnated as a slime) and I can watch the video on each of the 2 mirrors there and do not get the high CPU usage.

    I check my video players to see if it causes the high load. It doesn't seem to be the video player is causing the high load but the pages itself is spiking very high. A staff member will address the issue of the bug soon.

    Please use the edit button if you need to add additional info and no one has responded to your thread or most recent post. The edit button is located in the bottom left part of your posts.

    I've taken a look at "That Time I Got Reincarnated As A Slime" and "Goblin Slayer" and I'm not receiving any high CPU usage, so I'm unable to locate the exact cause of your high CPU usage. I check the last series you listed, "Death march ..." and could not locate the source either.

    If you are using Chrome as your main browser, visit the page that the high CPU usage happens. Use the key combination Shift + Esc. This will open Chrome's task manager. It should automatically highlight the current tab's process. Scroll down until you see it (but do not click on anything). The highlighted tab should list subframes, which are open processes that the page you visited has connected to. Please list all subframes or take a screenshot of all of them until you get to your next tab's process. Should look something like this:
    [​IMG]
    Since the Goblin Slayer tab is the most recently opened and the last tab that was open, it was at the bottom of the list and the extensions I have installed were listed. Notice that underneath the episode's tab are 3 subframes. Those are the open connections to 3rd-party websites. I will need to see that list that your browser has.
    Video hosts are as follows: MP4Upload.com, MP4Cloud.net and OpenLoad.co
    Our embedded community chat is chatango.com.
    Any other subframes that are unknown sites could be the source of your problem and will be the focus of my investigation into the issue.

    The page itself is giving out high CPU maxing out 100% of 1054.5. It might be the ad tag on the page what cause the issue. The one with the nhsrv.cf is part of mp4cloud.net giving out only 20% less that is safer for a user experience and doesn't detect by antivirus

    I'm getting the same as Tokyosama, the page itself has the high CPU usage. Also sorry about the multi posts. I will edit from now on to add more info to the original post.

    I'm still not receiving the same issue both of you are seeing, so I'm attempting to fix this pretty much blind at this point. I disabled some sections of the site, check the page again and let me know if the high CPU usage is still there on both the site and the "nbsrv" site in a subframe or if the "nbsrv" site is gone and the page is using a normal amount of CPU.

    I'm unable to determine what's opening a connection to nhsrv, especially since the domain doesn't seem to actually exist and it's not showing up on my end. Anyone that has nhsrv.cf listed in their browser's task manager may need to scan their computer for any malicious software as whatever the cause is could be on your computer and effecting the browser.

    nhsrv.cf is safe as it doesn't give out high CPU. It is not malicious software, therefore, doesn't detect by antivirus. Whatever is causing the high CPU will mostly be the ad tag on justanimenetwork. This is only related to the page on justanimenetwork, not mp4cloud. Mp4Cloud has already been fixed a while back ago.

    No process should be higher than 20.0 with the exception of the GPU process, which handles most of the visual processing and depends if you are streaming video or not. You shouldn't see a memory usage higher than 500,000K on website processes, and even then it's only been through media intensive sites like YouTube when it's streaming a video and storing the buffered data into memory and releases unused data when the page changes. Out of all the tabs I have open, only 2 of them are above 200,000K. Every tab I have open might only use about 10.0 once in a while after it has fully loaded, the streaming site has only peaked at about 12.4 while playing a video because of mouse over events over the tabs. MP4Cloud peaked around 26.5 to process video and player instruction on a mouse over event: revealing video player controls from it's auto-hide state. I have never seen a site use more on a constant basis like I have with this "nhsrv.cf" subframe.

    For a domain that doesn't appear to exist (nhsrv.cf) and it's purpose is completely unknown, it's storing a lot of data into memory and using way too much CPU on a constant basis. 137 is well above normal for any site that is inactive or is not processing instructions from the user. On top of that, entering that in a URL scanner reveals that at least Kaspersky picks up "nhsrv.cf" as malicious.

    nhsrv.cf is can be killed/blocked using the browser's task manager without effecting video playback.

    Everything also appears to be functioning normally for me as well. I checked various shows and it is not happening. I never got the nbsrv to show up on my task manager so I cannot say anything regarding that. If it helps since it does not happen to you maybe turning on each item you turned off one at a time and let us know to see if it starts happening again? To help narrow down which function you turned off is causing it.
