how to speed up curve-movement?

Hi, my cutting machine can do arc movement rapidly,
yet it's very slow when it comes to drawing a curve ( consists of a series of points) .
could anyone help me to improve its speed at drawing curves?

i attached the g-code in my experiment, changing the feeding rate did not help much.
the slow parts are the "g01 xxx g01 xxx g01 xxx g01 xxx g01 xxx ”.

the interpreter reads only 3lines ahead max is 10 lines on feather
so why are there small g01
normal postprocessors output only a min of 5m dist per line
or a G02/G03
you can get more speed on G64 P0,1 this will round the lines together
be awar on a high value Metric 1.0mm G64 P1
a 90deg Corner at 5000mm/min turns into a R20 Radius

THIS IS A 4th AXIS G-code
so your ACC of the 4th Axis might be so slow
can you get the INI inside
look here at 2:35min
its ACC 1200Deg/sec²

Just look at some of the first lines of g-code
What are those number 175, 176, 177 and 47,48,49 etc? Are they part of the X/Y coordinate - I didn't know there could be spaces in a number. Get rid of them. Or concat it into the number, whichever it should be.

Because these are moves that involves both A and XYZ coordinates the naive trajectory planner will be used and only one line of lookahead. I would think it is difficult to keep doing mm-long moves at 10000 mm/min with that trajectory planner.

I see two options, not very good ones. Don't use A axis. Or, optimize the g-code to take as long and few steps as possible.

Change the post processor or CAM software, that is not normal gcode.

Is there a filter option for your tool path?
Usually you can convert to arcs on some cam systems
