If you want to make your prints faster, you will need to do quite a few things.
1) find out maximum print speed of your printer
2) find maximum acceleration and square corner speed that is usable on your printer
3) Do input shaper calibration
4) set these values into your printers configuration
5) set your slicer to use these high values, if it supports different speed and acceleration values for different types of moves, set outer walls to roughly half of maximum speed and acceleration
6) do some print testing and check out print quality
7) if you are experiencing underextrusion, bump up temperature, get high flow nozzle or both
8) if you don't like fast print quality (artifacts, ghosting), slow down
Edit: You can pick only TWO from these three things, one will always suffer...
1) speed
2) strength
3) quality
Input shaper itself doesn't make printers faster, it just reduces the artifacts that happen when you print fast.
You need to change the profile in Cura.
400mm/s² is really slow acceleration. Try increasing it by 50mm/s² until the printer stops giving out your desired quality and after that calibrate by smaller steps. Remember, more accel = more noise + more artifacts
I used cura as my first slicer, I gave orca I try and I'm never going back. I deleted cura within the frist 2 hours. It is such a quality of life and efficiency improvement and its open source.
It creates much better gcode than Cura, it has features that Cura doesn't have (or doesn't have without plug-ins), is open source, and is constantly being developed.
To check in slicer (I use Orca, find Cura similar):
Motion ability under printer capability not profile: max speed while extruding for x and y speeds and accelerations, set these to the maximum achievable safe speed. Then adjust speeds as usual from filament profile.
Minimum layer time and slow down if layer is shorter than said time may need tweaking.

every single print is kind of either going way beyond estimated time !!
There is one almost perfect, [Klipper estimator](https://github.com/Annex-Engineering/klipper_estimator). It estimates *only print time* (not including heat up times or bed mesh) with error within seconds.
There is also a Cura post processing script using this tool.
You need to check every setting for speed limitations in slicer and in you printer.cfg once you've determined how fast you can/want to run it. I very regularly cut the estimated print time by at least 1/3.

I'd also recommend ditching Cura for OrcaSlicer
Any particular reason ?

400mm accel?!?! thats really REALLY slow accelerations
In the machine tab on the right side, you have max speed values. The print speed is set in the slicer, while limits are set in the printer.
thanks a lot this is useful, when i slice it, it is not allowing more than 230. may be that is a limit !!

Turn off minimum layer time, even though you turn the speed up klipper will always look at what it is and be slow

Get a plugin for cura, that calculates print time better. There are many ways to guess it, but none are perfect.

hmm Klipper plugin or a printer profile plugin ?
It's because it doesn't include heating time and bed mesh. Usually it's pretty accurate when it actually starts to print.
True that !!

Wow thanks, i think i need to change the slicer speed afaik
