Shat's Chrome doing?

I was checking why my PC seemed to be hesitating when opening a new tab or
responding to a tab update. When I looked at Task Manager I noticed that
Chrome had processes out the wazoo. At the time I had Chrome open with one
window aimed at This Old House TV. I counted 28 separate sub processes
running some sort of Chrome process. For one window! What the h**l, Chrome?

Is this a subscription TV thing, or is the
URL available for public viewing ?

Chrome will fork isolated containers for things
like Flash videos. If the page has multiple
videos, perhaps there is a process per video ?
A good web page design prevents all videos on
the page from playing at the same time.
(They can load and then wait their turn.)

It's also possible that some analytics code is
running *per advertiser* for that web page,
so the loading is just for bookkeeping purposes
by the web site in question.

If Chrome has been running for days on end,
they could be orphan processes (due to a Chrome
bug). In which case, you'd exit Chrome
normally, use Task Manager to find and remove
any stragglers, then repeat the test case and
see if 28 sub-processes open again.

I doubt Sysinternals Process Monitor would help,
because all the reads and writes would be to
obfuscated filenames, and you wouldn't know what
it was actually doing.

You could use Sysinternals Process Explorer, use
Run As Administrator on it, click on a Chrome process,
do Properties and look at the threads or stack info.
There's a vanishingly small chance of seeing
something interesting there.

The next level after that would be WinDBG,
and without .pdb files to use, you likely would
not learn a lot. Building Chromium from source,
would give .pdb files and allow debugging, but
without the exact logic that Google uses in the
closed-source Chrome version.

You can use Sysinternals TCPView to see what
IP addresses are open. But there isn't going
to be any nice mapping info to aid in your
quest. You still won't know what it's doing.

At the time, you had one tab open. How about before (within that
session of Chrome)? As you open more tabs, more processes will load.
Those processes do not immediately go away because you removed some
tabs. I don't know the algorithm but it can take a long time before
those processes get freed (exited) after removing tabs.

When you are done using Chrome, you should exit it instead of leaving it
running all the time wasting resources when it would otherwise be idle.
Also, script-heavy pages can slow how fast tab processes get unloaded.

Also, Chrome works by isolating a process for each extension. If you
installed lots of extensions, you'll get lots of processes even the
first time you load Chrome and even if you open it to a blank page
(about:blank).

A lot of processes. And that would be how many? When I load Chrome to
a blank page, there are 15 chrome.exe processes. Besides the base
processes for the web browser itself, it has to load processes for each
of the extensions that I installed which is 11 of them. So, out of
those 16 processes, 11 of them are just for the extensions. That means
there are only 4 processes for Chrome itself.

You can go to Chrome's own task manager to see what each process is for:
in Chrome, go to menu - More Tools - Task Manager. Read:

Chrome may also continue running "web apps" in the background after you
closed a tab where it was used. I have an Amcrest web camera that
installed a web app but I only want Chrome to be running it when I am
actually viewing the camera via the web. Web apps will continue running
even after you exit Chrome. As I recall, the installation of Chrome
will install several web apps for Google Docs whether you use them or
not. I don't so I uninstalled them as they would be a waste of
resources for me. Go to chrome:extensions and see if there is a section
titled "Chrome apps". To eliminate the background running of web apps,
go to menu - Settings - Advanced - System section and turn off the
"Continue running background apps when Google Chrome is closed" option.
When I exit Chrome, I really do want all of it exited. Read:

A lot of chrome.exe processes does not mandate a slowdown of your
computer. I have Chrome loaded right now with two tabs open which
results in 15 chrome.exe processes; however, every one of them has zero
CPU usage. Just because a process is loading doesn't mean it is doing
anything of consequence. You said there are a lot of chrome.exe
processes but you never mentioned if you clicked on the CPU header to
sort by CPU usage to see which process(es) were consuming the most CPU
cycles (and, no, the one labeled System Idle Process is NOT a real
process but just the remainder from 100% after deducting CPU usage for
all the other processes - CPU usage must add up to 100%, so System Idle
Process tells you how much is unused).
