Just an old 2-basin kitchen sink ...

the flat section of line after the trap is likely sluged up. why not
take it apart and check or use a low cost snake to clean it out.......

my best friend had a problem like yours, he called a plumber, the flat
area of the line was smaller than a pencil......

Wasn't always slow. The stuff I tried this time worked last time.

Damned True Value snake won't even fit thru my drain. A little
Zip unclogger brought up very little slime.

If it gets a bunch worse, I'll rent a real snake.

Yes, a snake.  Sometimes you get a clog that the chemicals just won't
move.  Put a real wire snake down there and find it.  The chemicals
are AOK for the trap, but the clog may be a few feet down the line.

Our bathtub drains slowly after some 6 or more months of regular use.
No kids, no long hair.  Snaking doesn't help, Drano-like stuff doesn't
help much either.  There is a long stretch of horizontal pipe in the
floor that I should have had replaced when the kitchen ceiling was open
- it has ~3 stretches of different materials of pipe.  Sludge
accumulates in the pipes.  The best way to remove it is to block all
opening and run water, then do some heavy duty plunging to loosen and
flush the stuff.

Does it flow slow from the get-go,
    If not how much water has to go down the drain before it slows down or
stops?
The volume should tell you how far down the pipe you may have a blockage.

One of the more useful tools for clogged pipes are drill operated drain
snakes

The smaller ones that can be run with a drill are inexpensive and will
address 70+% of the problems
For the rest just rent a professional one

They come with removable heads to  attack different problems
These will clean out 2" or bigger pipe
They can even chop up rootlets invading the run to the sewer



Alternately, your drain pipe may just be clogged with gunk on the sidewalls

My parents old house, Dad used to have to use a drain snake every few years,
to cut through the grease build up. You may have to do the same.

Just an old 2-basin kitchen sink. We ripped the old copper drainpipe out
maybe 4 years ago, installed ~ 5' of pvc.

Drain runs slow. Works, but obviously only 2/3 of capacity. I start
with bakg soda and vinegar, then some crystal Drano, then the pot of
boiling water, then the plunger. No noticable effect.

Any ideas?
