[SOLVED] Chromium uses only one cpu core when launch

tleydxdy · 2017-11-12 13:50:00

Running kernel 4.13.11-1-ARCH, Ryzen 1700x, Chromium 62.0.3202.89. htop shows that Chromium is only using one core (100%) and was extremely slow at launch.

Try running it from the command line and see if it prints out any helpful informaiton. Check the journal when you launch it and see if there is anything reported there. Try a new profile to eliminate any possibility of a problematic addon. If you're using any gtk 3 theme other than the default, try switching to the default and see if you still have the problem.

When launching normally the terminal output and with --user-data-dir=/tmp/chromium(a copy of my .config/chromium):

ATTENTION: default value of option force_s3tc_enable overridden by environment.
[31060:31060:1112/092945.086148:ERROR:sandbox_linux.cc(346)] InitializeSandbox() called with multiple threads in process gpu-process.

It didn't create any entry looking at journalctl -r
and with --user-data-dir=/tmp/chromium(a empty directory) there is no terminal output and things went superfast.
It didn't create any entry in journal either.

I then deleted all my extension, reset the settings and all the flags in chrome://flags, it launches as slow as usual, and output the above lines in the terminal.

I'm not sure why you copied your profile to /tmp, but if that resulted in a faster launch, then perhaps there is a problem with the filesystem that ~/.config/chromium resides on, or the hardware beneath that. The terminal output changing depending on what filesystem the profile resides on is odd too, and not something I can reproduce..

Sorry about my poor english, what I found out was that when I'm using a empty profile directory, things do launch faster. However, reset settings doesn't make chromium launch faster.

edit: creating a new profile didn't help either, as long as I have log in to my google account once.

After clearing sync data(backup bookmark etc), remove config file, pacman -Rsn chromium, reinstall chromium and import bookmarks, things still launches slow. after I remove about half of my bookmarks, suddenly the slowdown disappeared. So I guess this is solved.

Note, chromium will freeze randomly after this, not sure what happend.
