I've been using the Chromium browser and the experimental GL desktop on Raspbian Stretch for a couple of weeks now, and it works much better than under Jessie. Still, Chromium (and the entire desktop) become somewhat sluggish after a few hours' running, restored to normal by restarting Chromium.
Is anybody else observing this, and are there any workarounds?
Thanks for reading,

Well apropos of not a lot, my whole PC damnn near froze...when I managed to get a diagnostic tool running Firefox had eaten 8GB of RAM and 2GB of swap.
That was what was left over from logging in to online HSBC banking. Nothing else was running.
All browsers are irremediable shit, these days.

I find Seamonkey (another Netscape fork) to be not so bad. But it eats 100% CPU for up to 30 seconds while I wait for a response from our company's webmail server, which is also irremediable shit. (Accessing the same server via IMAP is lightning-fast.)

And what's wrong with using Flash Applets?
Here, the probable culprit is the webmail HTML page, and possibly the convoluted Javascript in it. There are page generator-built web pages thet contain immensely cryptic Javascript. The browsers do small miracles opening and interpreting them so quickly.
Just have a look at the webmail page source (Ctrl-U or CMD-U on many browsers).

Well, they can, I programmed some webserver interface for some things running on my pi. However the amount of resources the browser grabs are immense and slow things down. So for the same application I wrote a small app in C that runs on any Linux computer and connects to the main program, it is only xr-xr-x 1 root root 31268 Sep 9 2017 /usr/bin/xgpspc_mon yes 32 kB (kilobyte) and does everything the browser does, and more, and faster.
The browser as user interface is what Mickysoft Widows started using long ago, talk about senseless bloat. Java sucks.
I left both options in, in the main program, so somebody from somewere can connect with a browser, at least the system load in then theirs.
The other thing my app does is send the screen stream to stdout in YUV format, so you can make a movie of whatever happens all day; xgpspc_mon -y | ffmpeg -f yuv4mpegpipe -i - -f avi -vcodec mjpeg bp340.avi
Try it with a browser...
But then again, you need to know programming in C, Unix, and the tools.
Never done that IFAIR.
Bit ancient is it not?
On my PC I have created 3 buttons on a virtual desktop, to set the priority (niceness) of seamonkey,
0, -1 and -19.... If I REALLY get bored watching a site being drawn I hit the -19 icon,,,, Maybe because there is a lot of important stuff running (network related) that I normally run it nice -1.
Negative. Any browser I have used in the past has memory leaks and thus eats up ever more RAM, the longer it runs. As I don't shutdown my PCs but merely suspend them, I will have to eventually kill the browser to keep the system usable. Scripts, that's another hopeless issue. I recall when Mozilla promised a lightweight, quick browser. What a joke that became. All browsers are irremediable shit. BTST.
I am using w3m whenever I don't need the graphics. w3m never ate up my RAM.
Oh yes, the Windows Desktop Update and Internet Exploder 4. I thought it was a nice improvement to the Windows NT4 interface (obviously avoiding the Active Desktop nonsense).

Possible, I switched to Linux after win98 in 1998. Win3.1 I had before that was on top of DRDOS on my PC. To kill DRDOS (competition, it was better than MSDOS) mikysoft did some strange things in WIN98 (killed some of my games). One day I came upon a CD with SLS Linux, had a free C compiler (gcc), and never went back. Somebody once recommended Xp to me, and I was stupid enough to buy that, burned it and made a movie of it. On my new Samsung laptop was also windowns, that made way the same day for Ubuntu.
So I am by no means expert on that redmond crap, never ran NT.
Do you mean Java or Javascript?
I can do exactly the same with C (ncurses) or Java 8(Swing or Jcurses) but without needing any other assist than SSH with X11 forwarding enabled.
I have several desktop Java applications, all using Swing to implement graphical displays. None of them are particularly big (133 - 179K JAR files) The most complex is 130k (4000 statements) but that is a full- screen club roster management tool. It builts 6 months-worth of weekend club rosters: 15 people a day on six different rosters and runs fast enough for the lag to be unnoticeable on an i5 laptop. It is almost as fast when run on a dual Athlon desktop using X11 forwarding to see and control it from a laptop on my LAN. It is compiled and run under OpenJava
1.8The others are Java programs, also using Swing, and built to query a PostgreSQL database across my LAN.
In summary, X11 forwarding is the way to to if you want to display graphical material from a program that's elsewhere on a LAN - doesn't matter whether the program is graphical or console oriented or how its generating the graphics - X11 forwarding handles the lot seamlessly without needing any specialised code.
I do this with my RPi as well. Mine is run headless and has always been accessed over remotely via SSH, though I don't use any visual interface more complex than Curses for programs running on the RPi - never seen the need for that so far given the type of programming I use it for.

Yes I use ssh -Y to my raspies from the PC, those are not even connected to a monitor or mouse. Also for program development.
An other thing for connecting things over the LAN or world wide is 'netcat' (also called 'nc' sometimes). Try on a computer with IP address XXXX netcat -l -p 1000 | tee myfile
and then on an other computer: echo "hello' | netcat XXXX 1000
Using pipes via netcat you can send video, netcat -u for UDP streaming is also possible.
But really, writing a simple webserver interface for your program in C is not such a big deal either, examples on my site. Plenty of help for that online too, use google. When I started with Linux in 1998 there were few program available, had to write about everything myself, even this Usenet news reader:
Guess it is in the genes or something, was fixing a bug at 2 o'clock last night. Was one of those rare silly errors in presentation that only happen once in many days if not years, not been able to reproduce the same situation... depends on incoming radio signals. Have to make simulation test files....
Unfortunately in doing so they (and web pages in co-evolution) have become poor at doing what they were originally designed for - displaying information, unstable resource hogs and a mess of security issues.

I for one won't use Flash, and haven't ever since there have been credible alternatives. Its got far too many hacker-friendly coding mistakes in it for my taste and is either:
- so badly written that its unrepairable
OR
- Adobe has never had any intention of doing more than the bare minimum to stop users from walking away
....your choice of which to believe.

What Martin said but also more directly: not supported on mobile, often blocked on desktop.
Flash is horrible, like Postcript, but it was the first and for a time the only standrad and so one needs to be able to accomidate it.
