after 0.20.x update Brave is slow/sluggish #13087
Comments
|
Has happened to me 2 times after just opening the browser and one time from using it for like 30 minutes. |
|
Restart always fixed the problem for me on Windows: |

Maybe related, maybe not: Brave grinds to a halt (like taking seconds to register clicking on a tab) when it goes into a crash loop as described in #12995 and a restart fixes it. Perhaps other slowdowns are caused by similar crash loops? |

Same issue: Is there a way how can we help to nail down the issue? Like enabling additional logging? |

This has been driving me crazy recently. Eventually YouTube playback is as slow as a first-gen MacBook Air and just today it's become all-together unresponsive at some point, new tabs open in the tab bar but never produce a window, clicking on inputs takes ages, etc. etc. Relaunching Brave does indeed fix the issues temporarily. |
|
When this problem occurs for me (on Linux), I can almost everytime see in the task manager that there is one of Brave's subprocesses ( I hope Brave does not do cryptomining in the background.. |
|
I'm running into the issue as well.
As opposed to relaunching Brave - if I close the lid on my laptop and re-open to wake the computer back up, it resolves the issue for 1-2 days before it is noticeable again. |

Wanted to sound off hear as well. Experiencing very similar issues. Details: Brave: 0.20.30 Some days it takes only minutes for Brave to start slowing down, others it could take a couple hours, but it always seems to slow down at some point. Behavior results in an extreme lag in switching or opening new tabs (sometimes as long as 10 seconds, others shorter but still very noticeable). Additionally, I start to see even a delay in text recognition, where I will start typing and the browser isn't picking it up until after I've gotten halfway through a sentence. I haven't noticed any spike in CPU usage through Activity Monitor, but it does seem as though Brave begins to slow down all processes on my machine when it's begun to slow down. |

I'm seeing the same issue on Windows 7. I think it may be related to a memory leak. This did not happen in earlier releases.
After having Brave open for some hours, it becomes unbearably slow. I noticed that the Brave.exe processes were consuming well over 1.5 GB of RAM. After closing all but one tab, and then changing that one tab to be about:blank, there were still three Brave.exe processes consuming 1.5GB of RAM! See the attached screeenshot.

STR

This was causing an error to be thrown for every subsequent action, and no more state updates to be sent to windows, resulting in multiple issues. It was also causing an error dump to be generated upon every action, thus halting the browser at those times, including any audio/video (and creating stutters). Fix #13079 (main test case with STR) Fix #12333 Fix #12828 Fix #13157 Address #13087 but this is a broad issue - this change will fix a hard issue, whereas that refers to general slowness.

Test Plan
Description
Reports of Brave being slow/sluggish/lagging after update to 0.20.x. Some users are experiencing slowness immediately after opening (@Jacalz on Windows 10) others are seeing the slowness after having Brave open for several days (@davidtemkin and @kjozwiak on MacOS). Sometimes a restart fixes the problem.
Steps to Reproduce
STR seem to vary: some users experience this immediately and others have had Brave open and operating normally for a few days.
Actual result:
Slowness and lagging
Expected result:
No changes to browsing experience
Reproduces how often:
Unknown
