chromium slow & slugish

Hi Archers,

just thought I would share my experience since upgrading to 47.0.2526.80-2

Normally I run chromium from a short key:

chromium --purge-memory-button --memory-model=low

just to keep it in check & I have used this for quite sometime, however I upgraded today to the version mentioned above to find it would site there at 100% cpu for at least 5 minutes upon start & would jump to 100% during any search or scroll.
I checked htop & this told me too that chromium was the culprit.

I then rerun from terminal with no extra switches & also set --user-dir to a fresh new folder for a fresh run to eliminate all extensions this did nothing.

I then decided to downgrade to the previous version & all my issues where gone.

Not sure of the cause but I'll stay at this version until the next one YMMV but I thought I would let you know & to see if others have the same experience.

Cheers

just thought I would update this.
I am now running 47.0.2526.106 (64-bit)

no longer use --memory-model=low as it is depreciated.

I have multiple user-dirs but still even when I compare the usage from my normal profile to a fresh one with NO extensions I still get the same results.

I note that prior to chromium migrating to 64bit I never had these issues but now I get the following:

On start CPU jumps to 100% & stays for about a minute & during this time I can type but do not see anything & then after a minute it prints the text in bursts & then usage drops off but text display of what I typed is still being shown.
When I go to a page (any page) usage jumps back to 100% & mem usage fluctuates from 400Mb-1.5Gb depending on content/site being loaded.
When page is loaded scrolling affects CPU usage (as normal) but when it loads dynamic content CPU is pegged to 100% & other apps begin to be affected.

I have monitored journalctl -f & this shows NO errors
I have tried the debug output of the browser but I have no clue as to what is normal or not.

I have also reinstalled the browser multiple times but the issue remains, this does not occur with other browsers

To which version did you downgrade?

Would you happen to have installed anything from the aur for flash/pdf support? Also try with a new user, not just a new profile, it shouldn't matter but just for the sake of eliminating as many variables as possible.

I forget the exact version but at that point in time it was the one before it went 64bit

No, I don't use flash & pdf I view in foxit. I get the same performance with a different user, I do not think this is a system issue either because I have tried various live cd's & dual boot with windows & it does not follow.

Just at a total loss as to what the cause is.

If the problem is only with arch then it must be something specific on how arch builds chromium or specific to your install, I am inclined to say that there is something different with your install that causes this, otherwise we would see a lot of complaints about this.

The only things I can think of right now are either some sort of trouble with ipv6 (every once in a while ipv6 is the root cause of some problems) or you are missing something in your hosts file (127.0.0.1 line and/or ipv6 equivalent or missing/bad nsswitch.conf configuration). Even if these guesses are not correct it must be something at the system level since it affect all users on your machine.

Chromium runs fine here on a i7 32GB nvidia 610 desktop. I also enable full h/w acceleration as well via the flags.
