That's good you were able to fix it. A country's government
interfering actually did cross my mind. We're an international list
here. We never know what kind of "censorship" or other interference,
e.g. even eavesdropping, that our fellow list members might be
experiencing at any given moment.

Am writing now to add on something else that also crossed my mind last
night. In my case, I've poked around in not one but two vpn (virtual
private network) [concepts] on my newest setup. I started tinkering a
little with those about a week ago and am *pretty sure* I've disabled
them, but I won't swear to it, grin.

*In my case*, the browser based vpn VERY MUCH slowed things down
immediately. It was so slow that I toggled it right back off, but
things haven't felt 100% back at the previous state ever since.

Anyway, just throwing VPNs out there, both browser based and stand
alone software, as another conscious point to check off one's Internet
speed debug checklist if anyone happens to come across this thread in
the archives. :)

i am afraid china's firewall cause it
it can filter Packages easily
but with binary data, it is not so easy
government's firewall is very advanced

You are aware I hope, that the sun cut loose with a good sized solar 
flare, and that communications all over the planet have been somewhat 
disrupted since around this past Wednesday? Not a Carrington sized 
event, but disturbing. You can google for Carrington Event, or look it 
up on wikipedia.  Another like that one and the whole planet will be 
dark at night until we can rebuild it all.

I've been having the same issue with Internet access (via dialup), but
the experience is across most of the entire [Net] for me. It's been
maybe a week or so that it has been very notable. It's been so bad a
few times that I've dipped into my reservoir of not so pretty words a
couple times along the way...

Ditto what Felix said about running both until you see if you like the
newest edition. I'm actually about to deliberately debootstrap Stretch
soon again just for practice. It will be my backup since I moved to
Buster during the newest release.

I consciously keep both because I always have it in mind that maybe
someone will have a problem with the previous release and maybe, just
maybe I'll be able to duplicate their issue to try to help out. I
actually was able to do that a couple months back where no one else
could duplicate a user's error, and my setup actually did throw the
user's same issue. *yay* :)

There was a thread here, yesterday I think, explaining that a fresh EXT4
partition isn't completely formatted initially, and depends on the CPU finishing
the task in the background after mounting. I suppose that this process could be
slowing other things down until completed.

I know little about Internet in China, but have heard that the government
manipulates the user experience in terms of what is available and the traffic.

This is true, but also it is not easy when a new release frustrates.

 Right. This is caching. It can be very helpful in limiting waste of bandwidth.
An uncached package can be slower coming from longer away through a slower pipe,
and may additionally be slowed by censorship and/or malware inspection.

Can you use GParted? That works great. You can shrink a partition on a 
drive that has enough space, and make a new one in the resulting empty 
space. Format the new partition,
with a Linux file system. Then you can make a directory on the the new 
partition and copy files by any of the normal means from your existing 
partition to the new one. Best if you
have two drives, so put the new partition on the second drive, so now 
you have a nice backup.

Which filesystem type do you have for /? How long ago did you
install? Was
Stretch a fresh installation, or an upgrade from Jessie?

> i regret i install stretch
> (i am happy with jessie)

I like Stretch better, though not that much.

Next time, install another alongside, in multiboot, instead of
replacing. Then
if you don't like it, just don't use it. If you do, good, and the
old one can be
a rescue tool, and a place to install the next new version.
